[R-SIG-Finance] [R-sig-finance] timeDate conversion [C1]

[DavidM.UK]

If you're dealing with tick data (which is usually extensive) I'd advise you
do any time/date processing outside of R.  My suggestion would be to use
Perl to format the dates and then read the data into R, this is how I deal
with tick data at least.

Best,

David
