Author: leonardo

New Revision: 6908

Modified:
   trunk/gs/src/gdevpdf.c
Log:
Fix (pdfwrite) : More PDF/A-1b complience, continued 6.

DETAILS :

Bug 688783 "commit 6892 mis-uses the TZ environmental".

Completely removed the time zone computation because
it's not working properly with some compilers.
Always write the UTC time instead.
It looks compliant with all PDF/A, PDF 1.6, ANSI C and 
http://www.w3.org/TR/NOTE-datetime standards.

DIFFERENCES :

None.
