 Possibly, though they are related to different functions. The issue here
 is that get_date_from_gmt() assumes that the current timezone offset
 equals the timezone offset for whatever time-string it is given. The issue
 with #9825 is that get_gmt_from_date() is doing the same thing in reverse.

 I think having a get_gmt_offset() function would help fix both of these,
 rather than having separate timezone-handling code in both of
 get_date_from_gmt() and get_gmt_from_date(). The main problem is that
 currently any use of get_option('gmt_offset') assumes that we're dealing
 with the present.
