* The time is always stored in localtime with the
* timezone offset being what get added to GMT to
* get to localtime. Thus we need to subtract the offset
* to get to true GMT, which is what we store the time
* as internally. On the local system, the user may set
* their timezone any way they wish, of course, so GMT
* gets converted back to localtime on the receiving
* system.
*
* NOTE: mkisofs in versions prior to mkisofs-1.10 had
* the sign wrong on the timezone offset. This has now
* been corrected there too, but if you are getting screwy
* results this may be the explanation. If enough people
* complain, a user configuration option could be added
* to add the timezone offset in with the wrong sign
* for 'compatibility' with older discs, but I cannot see how
* it will matter that much.
*
* Thanks to kuhlmav@elec.canterbury.ac.nz (Volker Kuhlmann)
