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 [1] "2006-12-01 01:02:00 EST" > strptime("20061201 1:02 PST",format="%Y%m%d %H:%M",tz="")+0 [1] "2006-12-01 01:02:00 EST" > strptime("20061201 1:02 PST",format="%Y%m%d %H:%M",tz="GMT")+0 [1] "2006-12-01 01:02:00 EST" > strptime("20061201 1:02 PST",format="%Y%m%d %H:%M",tz="UTC")+0 [1] "2006-12-01 01:02:00 EST" > strptime("20061201 1:02 PST",format="%Y%m%d %H:%M",tz="EST")+0 [1] "2006-12-01 01:02:00 EST" What is the recommended way of handling this? Computing and adding offsets manually? > strptime("20061201 1:02 PST",format="%Y%m%d %H:%M",tz="UTC")+3600*3 [1] "2006-12-01 04:02:00 EST" Or am I doing something wrong with the strptime(..., tz="EST") function?
