Hello,
Try this:
> testtime<-("2013-01-01 01:00:01 PM")
> strptime(testtime, "%Y-%m-%d %I:%M:%S %p")
[1] "2013-01-01 13:00:01"

Readers,
For a 12 hour time stamp:
testtime<-("2013-01-01 01:00:01 PM")
testtime
[1] "2013-01-01 01:00:01 PM"
testtime24hour<-strftime(testtime,'%H:%M:%S')
testtime24hour
[1] "01:00:01"
how to convert to 24 hour format so that the object 'testtime24hour' is:
'13:00:01'
Thanks.
