A cleaner example (half the comparisons) of distanceOfTimeInWords() function below:
<?php
public static function distanceOfTimeInWords($fromTime, $toTime = 0, $showLessThanAMinute = false) {

I took a different approach to a time difference. The current functions provided to not account for the different number of days in a month.
I have included a function that will calculate the start dates month and the number of days in each month thereafter. There are two things that I have
not yet taken into account. One is daylight savings time and the other is leap year. Perhaps someone can add that to this code.
function num_months($mon_start, $months, $work) {
while($work > 2419200) {
switch($mon_start) {
case 1:
case 3:
case 5:
case 7:
case 8:
case 10:
if($work > 2678400) {
$work = $work - 2678400;
$mon_start++;
$months++;
} else {
$exit = 1;
}
break;
case 12:
if($work > 2678400) {
$work = $work - 2678400;
$mon_start = 1;
$months++;
} else {
$exit = 1;
}
break;
case 2:
$work = $work - 2419200;
$mon_start++;
$months++;
break;
case 4:
case 6:
case 9:
case 11:
if($work > 2592000) {
$work = $work - 2592000;

} else {
$exit = 1;

}
if($exit == 1) {
break;
}

So I was looking for an equivalent of Ruby on Rails time_ago_in_words function. I found the TimeAgo function in the comments here, but it doesn't quite behave like the Rails counterpart.
In case you are looking or it as well, I've ported the Ruby code into PHP. Unfortunately, it doesn't look as clean as its Ruby counterpart, but it works the same:
<?php
/*
* PHP port of Ruby on Rails famous distance_of_time_in_words method.
* See http://api.rubyonrails.com/classes/ActionView/Helpers/DateHelper.html for more details.
*
* Reports the approximate distance in time between two timestamps. Set include_seconds
* to true if you want more detailed approximations.
*
*/
function distanceOfTimeInWords($from_time, $to_time = 0, $include_seconds = false) {
$distance_in_minutes = round(abs($to_time - $from_time) / 60);
$distance_in_seconds = round(abs($to_time - $from_time));
if ($distance_in_minutes >= 0 and $distance_in_minutes <= 1) {
if (!$include_seconds) {
return ($distance_in_minutes == 0) ? 'less than a minute' : '1 minute';
} else {
if ($distance_in_seconds >= 0 and $distance_in_seconds <= 4) {
return 'less than 5 seconds';
} elseif ($distance_in_seconds >= 5 and $distance_in_seconds <= 9) {
return 'less than 10 seconds';
} elseif ($distance_in_seconds >= 10 and $distance_in_seconds <= 19) {
return 'less than 20 seconds';
} elseif ($distance_in_seconds >= 20 and $distance_in_seconds <= 39) {
return 'half a minute';
} elseif ($distance_in_seconds >= 40 and $distance_in_seconds <= 59) {
return 'less than a minute';
} else {
return '1 minute';
}
}
} elseif ($distance_in_minutes >= 2 and $distance_in_minutes <= 44) {
return $distance_in_minutes . ' minutes';
} elseif ($distance_in_minutes >= 45 and $distance_in_minutes <= 89) {
return 'about 1 hour';
} elseif ($distance_in_minutes >= 90 and $distance_in_minutes <= 1439) {
return 'about ' . round(floatval($distance_in_minutes) / 60.0) . ' hours';
} elseif ($distance_in_minutes >= 1440 and $distance_in_minutes <= 2879) {
return '1 day';
} elseif ($distance_in_minutes >= 2880 and $distance_in_minutes <= 43199) {
return 'about ' . round(floatval($distance_in_minutes) / 1440) . ' days';
} elseif ($distance_in_minutes >= 43200 and $distance_in_minutes <= 86399) {
return 'about 1 month';
} elseif ($distance_in_minutes >= 86400 and $distance_in_minutes <= 525599) {
return round(floatval($distance_in_minutes) / 43200) . ' months';
} elseif ($distance_in_minutes >= 525600 and $distance_in_minutes <= 1051199) {
return 'about 1 year';
} else {
return 'over ' . round(floatval($distance_in_minutes) / 525600) . ' years';
}
?>
Additionally, here is the wrapper function:
<?php
/*
* Like distanceOfTimeInWords, but where to_time is fixed to the output of time()
*
*/
function timeAgoInWords($from_time, $include_seconds = false) {
return $this->distanceOfTimeInWords($from_time, time(), $include_seconds);
}
?>

It should be noted in the example, that time() + (7*24*60*60) and strtotime("+1 week") do not always generate the same timestamp. The problem occurs when the daylight saving time changes.
Therefore it's usually better to use strtotime..
Example:
the last time the time changed in the Czech republic was on the 30th March 2008, from 2:00 to 3:00.
Assume it is Wednesday, the 26th March 2008, 23:59.
If you call
<?php echo date("l, jS F Y, H:i",strtotime("+1 week")); ?>
you get Wednesday, 2nd April 2008, 23:59, as you would predict,
although if you try
<?php echo date("l, jS F Y, H:i",time()+(7*24*60*60)); ?>
you get Thursday, 3rd April 2008, 00:59. Here's where things might get a bit confusing, if you don't expect it!
Suddenly you find the food list for the next week is gone :D !

PHP is affected by the Y2K38 bug.
<?php
$current_time = time();
$years_from_now = 50;
$remaining_seconds = 60 * 60 * 24 * 365 * $years_from_now;
$future_unix_time = $current_time + $remaining_seconds;
$future_date = date('Y-m-d', $future_unix_time);
echo $future_date;
// 1921-11-05
?>
It is caused because the PHP uses the C 32 bits time function

My modification and enhancements to the timeDiff() function last updated by sean sullivan. The rewrite was done to add a couple new optional parameters but I also got a bump in performance. On a completely personal preference level I changed the month and year second values with ones I got from Google searches.
Written and tested with 5.2.0.
Options include
to = time(); date to compute the range to
parts = 1; number of parts to display max
precision = 'second'; lowest part to compute to
distance = TRUE; include the 'ago' or 'away' bit
separator = ', '; separates the parts
<?php
function timeDiff($time, $opt = array()) {
// The default values
$defOptions = array(
'to' => 0,
'parts' => 1,
'precision' => 'second',
'distance' => TRUE,
'separator' => ', '
);
$opt = array_merge($defOptions, $opt);
// Default to current time if no to point is given
(!$opt['to']) && ($opt['to'] = time());
// Init an empty string
$str = '';
// To or From computation
$diff = ($opt['to'] > $time) ? $opt['to']-$time : $time-$opt['to'];
// An array of label => periods of seconds;
$periods = array(
'decade' => 315569260,
'year' => 31556926,
'month' => 2629744,
'week' => 604800,
'day' => 86400,
'hour' => 3600,
'minute' => 60,
'second' => 1
);
// Round to precision
if ($opt['precision'] != 'second')
$diff = round(($diff/$periods[$opt['precision']])) * $periods[$opt['precision']];
// Report the value is 'less than 1 ' precision period away
(0 == $diff) && ($str = 'less than 1 '.$opt['precision']);
// Loop over each period
foreach ($periods as $label => $value) {
// Stitch together the time difference string
(($x=floor($diff/$value))&&$opt['parts']--) && $str.=($str?$opt['separator']:'').($x.' '.$label.($x>1?'s':''));
// Stop processing if no more parts are going to be reported.
if ($opt['parts'] == 0 || $label == $opt['precision']) break;
// Get ready for the next pass
$diff -= $x*$value;
}
$opt['distance'] && $str.=($str&&$opt['to']>$time)?' ago':' away';
return $str;
}
?>
Usage:
$span = timeDiff($when);
or
$span = timeDiff($when, array('parts' => 3));

When dealing with the results of the time function, taking the modulus (remainder) is often a good way to find recurring information such as day of the week, week of the year, or month of the year. In the example given below of a firefighter's shift, you could do the following to simplify the code.
<?php
function whatShift() {
$referencePoint = mktime(7, 0, 0, 9, 11, 2004); // Sept 11, 2004 at 7AM started an A Shift.
//This is the where we divide the current time since reference by the amount of time in all shifts
//The result of this is the remainder.
$sinceReference = (time() - $referencePoint) % (60 * 60 * 24 * 3);
//The rest of the code can be basically the same so I shortened it here.
if ($sinceReference < 60 * 60 * 25) $shift = "A";
elseif ($sinceReference < 60 * 60 * 49) $shift = "B";
else $shift = "C";
return $shift;
}

Fire Fighters typically work one day on and two days off. Known as shifts and generally referred to as A, B and C. I need to compute this for a web script so I came up with the following function.
Notes: You may need to change the reference date as not all departments are on the same rotation. Also, this does not take into account daylight savings time so the changeover moves by an hour.
<?php
function whatShift() {
$referencePoint = mktime(7, 0, 0, 9, 11, 2004); // Sept 11, 2004 at 7AM started an A Shift.
$now = time();
// Next we need to know how many seconds since the start of the last A Shift.
// First we compute how many 3 days cycles since the reference point then
// subtract that number.
$difference = ($now - $referencePoint);
$cycles = floor($difference / (60 * 60 * 24 * 3));
$sinceReference = ($difference - ($cycles * 60 * 60 * 24 * 3));
if ($sinceReference < 60 * 60 * 25) { // Before the start of the 25th hour it's A Shift.
$shift = "A";
}
elseif ($sinceReference < 60 * 60 * 49) { // Else before the start of the 49th hour it's B Shift.
$shift = "B";
}
else {
$shift = "C"; // Else it's C Shift.
}
return $shift;
}

A function for converting to Unix time without using the MySQL UNIX_TIMESTAMP function in a query (MySQL allows eight different formats for timestamps):
<?php
function UnixTime($mysql_timestamp){
if (preg_match('/(\d{4})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})/', $mysql_timestamp, $pieces)
|| preg_match('/(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})(\d{2})/', $mysql_timestamp, $pieces)) {
$unix_time = mktime($pieces[4], $pieces[5], $pieces[6], $pieces[2], $pieces[3], $pieces[1]);
} elseif (preg_match('/\d{4}\-\d{2}\-\d{2} \d{2}:\d{2}:\d{2}/', $mysql_timestamp)
|| preg_match('/\d{2}\-\d{2}\-\d{2} \d{2}:\d{2}:\d{2}/', $mysql_timestamp)
|| preg_match('/\d{4}\-\d{2}\-\d{2}/', $mysql_timestamp)
|| preg_match('/\d{2}\-\d{2}\-\d{2}/', $mysql_timestamp)) {
$unix_time = strtotime($mysql_timestamp);
} elseif (preg_match('/(\d{4})(\d{2})(\d{2})/', $mysql_timestamp, $pieces)
|| preg_match('/(\d{2})(\d{2})(\d{2})/', $mysql_timestamp, $pieces)) {
$unix_time = mktime(0, 0, 0, $pieces[2], $pieces[3], $pieces[1]);
}
return $unix_time;
}
?>

I did an article on floating point time you can download from my website. Roun movements is the radial ounion movement and there is a quantum ounion movement as well, this code will generate the data for http://www.chronolabs.org.au/bin/roun-time-article.pdf which is an article on floating point time, I have created the calendar system as well for this time. It is compatible with other time and other solar systems with different revolutions of the planets as well as different quantumy stuff.
Thanks:
<?php

$gmt=-$gmt;

$roun_ya = $ptime/(24*60*60);
$roun = (($roun_xa -$roun_ya) - $weight)+(microtime/999999);
