in that case you need to know the time difference for the timezone of interest,
as described by hal fulton (in his ruby way).
TZ env doesn't help since localtime() syscall is called only once (i.e. it is
cached). but I think you can use the TZ env to generate a mapping between
timzeone and time difference with UTC.
