Hi,
 
I have two data sources. One records time in PST time zone, the other in
GMT. I want to compute the difference between the two, but don't see
how. Here is an example where I compute time difference between
identical times each (meant to be) relative to its time zone.
 
> as.POSIXlt("2000-05-10 10:15:00",  "PST") -  as.POSIXlt("2000-05-10
10:15:00",  "GMT")
Time difference of 0 secs

I was expecting to see 8hrs (which is the time difference between London
and San-Francisco). Why is it so and what is the correct way of doing
it?
 
 
I use R-1.8.1 on RH-7.3.
 
Thanks,
Vadim
