[Message part 3 (text/plain, inline)]

I'm running FreeBSD 10.1 (amd64). My /etc/localtime points to "Asia/Kolkata"
(Indian Standard Time, UTC+0530) timezone.

For "Date: Sun, 15 Feb 2015 06:42:44 +0000 (UTC)":

#v+
(encode-time 44 42 6 15 2 2015 0 nil 0)
=> (21727 62092) = 1423962764
#v-

#v+
>>> print gmtime(1423962764)
time.struct_time(tm_year=2015, tm_mon=2, tm_mday=15, tm_hour=1, tm_min=12, tm_sec=44, tm_wday=6, tm_yday=46, tm_isdst=0)
>>> print localtime(1423962764)
time.struct_time(tm_year=2015, tm_mon=2, tm_mday=15, tm_hour=6, tm_min=42, tm_sec=44, tm_wday=6, tm_yday=46, tm_isdst=0)
#v-

If it was "Date: Sun, 15 Feb 2015 06:42:44 +0530":

#v+
(encode-time 44 42 6 15 2 2015 0 nil 19800)
=> (21727 62092)
#v-

The expected output for the time specified in UTC should be:
(21728 16356) = 1423982564

#v+
>>> print gmtime(1423982564)
time.struct_time(tm_year=2015, tm_mon=2, tm_mday=15, tm_hour=6, tm_min=42, tm_sec=44, tm_wday=6, tm_yday=46, tm_isdst=0)
>>> print localtime(1423982564)
time.struct_time(tm_year=2015, tm_mon=2, tm_mday=15, tm_hour=12, tm_min=12, tm_sec=44, tm_wday=6, tm_yday=46, tm_isdst=0)
#v-

I've come across while trying to figure out cause for a bug[1] report while
ago.

Sure, but the modified test program has unspecified behavior in POSIX, 
as there's no guarantee that environ[1] is "abc" (it might be "mno").  
Whereas the original test program has well-defined behavior in POSIX, 
but reports an error because FreeBSD 10.1 getenv is buggy.

Anyway, Emacs now works around the FreeBSD bug so I'm closing this Emacs 
bug report.  Thanks for checking the fix.
