http://php.net/strtotime will convert it to a timestamp, then you can
subtract the appropriate amount of time (hint - in seconds) and then
reformat using http://php.net/date

Or you can use http://php.net/mktime after working out the current year,
month etc with http://php.net/date and then adding/subtracting the
appropriate hours and minutes etc.
