The result of strptime() is not affected by the current timezone setting, even though strftime() is. Tested in PHP 5.1.6.

If you need strptime but are restricted to a php version which does not support it (windows or before PHP 5), note that MySQL since Version 4.1.1 offers (almost?) the same functionality with the STR_TO_DATE function.

//This turns non-standard but often used "datetime" string

//like '20060810084251' into nice formatted date

//'Thursday, 10 August 2006 08:42:51 CEST'

//note, that strptime returns day of year counting from 0, so

//you need to put 1 as month number to get appropriate

//month for the daycount. for 2006 strptime for unknown

//reason returns 106, so I simply add 1900

It says "Parse a time/date generated with strftime()" but that's not entirely correct -- While strptime("2006131", "%Y%W%u") works as expected, strptime("2006131", "%G%V%u") returns false instead of reversing the equivalent - and unambiguous - strftime() usage.  I suspect that's because glibc doesn't support that.  Anyway, this docu page fails to mention that apparently not all format components supported by strftime() can be used with strptime().
