Subject: (PHP date) Added new 'O' format modifier for printing out the GMT Offset in
X-Git-Tag: PRE_METHOD_CALL_SEPERATE_FIX_PATCH~30
X-Git-Url: https://granicus.if.org/sourcecode?a=commitdiff_plain;h=4604031b84c100983cd2525b4043b0dba8e2f9e9;p=php

(PHP date) Added new 'O' format modifier for printing out the GMT Offset in
           the same manner as emails have in their Date: header.  The format
           is similar to [+-]HHMM of offset.
@- Added new 'O' format modifier that will output the GMT offset as "[+-]HHMM"
@  (eg: Pacific time is -0700).  This is useful for things such as Date: mail
@  headers.
#  Um, this should have existed LONG time ago...   much better than that gmt
#   offset in seconds modifier :)
