Best replacement for this function seems to be "date_parse". Note that the returned array keys change from things like "tm_year" to simpler names like "year". Fwiw, "date_parse_from_format" did not look like a good replacement to me---even though I updated my format string ("i" is used for minute instead of "M"), it returned errors for a straightforward format ("%Y-%m-%d %H:%i:%S").
