The number of seconds since the epoch is independent of the time zone. What depends on the time zone is the way this number of se conds is interpreted.

Maybe this session under ste Perl debugger will clarify what happens: 

  DB<1>  print scalar gmtime time
Tue May 14 22:27:51 2013
  DB<2> print scalar localtime time
Wed May 15 00:27:59 2013
  DB<3>  print time
1368570496
  DB<4> @c =  gmtime 1368570496

  DB<5> x @c
0  16
1  28
2  22
3  14
4  4
5  113
6  2
7  133
8  0
  DB<6> @d =  localtime 1368570496

  DB<7> x @d
0  16
1  28
2  0
3  15
4  4
5  113
6  3
7  134
8  1
  DB<8>

My apologies if I did not really answer to your question, I am not entirely sure what your problem is.
