Algorithm to exploit 32 bit time functions to do time zone calculations

Hi,
I'm writing to you in reference to your libtai library whose TODO file states
that "support time zones" is still todo.  I had originally considered using
libtai in Perl to avoid the Unix 2038 bug, but Perl requires time zone support.

Instead, I am rewriting the time.h library functions to be 2038-clean.  The
effort is located here.

The piece which is of interest to libtai is this:

I have figured out a way to make use of 32 bit system functions to do 64 bit
time zone and daylight savings calculations.  I thought you might be able to
apply this to libtai.

Thanks,
Schwern


PS  Any potential license issues I'm happy to work out.
