Hi All
In trying to correlate some tide gauge data I need to deal with varying
timezones. From the documentation on strptime, it seemed that the tz
variable might have some effect on the conversion, but I'm not seeing an
effect.
strptime(20061201 1:02 PST,format=%Y%m%d %H:%M,tz=PST)+0

Is EST a timezone on your system? You have not told us your system, but
on most the timezone in the Eastern US is EST5EDT, not EST. Similarly
with PST. (See ?as.POSIXct.)
Remember that strptime returns an object of class POSIXlt and that has a
'isdst' field. The timezone controls that, but
