[R] Change date time to epoch time

[Jeff Newmiller]

There are many epochs. Which one are you interested in? If you are interested in the POSIX time_t epoch, then you could look at ?DateTimeClasses to find out about ?as.POSIXct. You might also find my email on inputting zones informative [1].

Also, per the Posting Guide, please don't post in html format... it messes up your R code.
