I think this is a problem with difftime (which gets called when the
subtraction in your example is invoked). The first few lines of
difftime are:
function (time1, time2, tz = , units = c(auto, secs, mins,

{
time1 - as.POSIXct(time1, tz = tz)
time2 -

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
