with_tz: Get date-time in a different time zone


with_tz returns a date-time as it would appear in a different time zone. The actual moment of time measured does not change, just the time zone it is measured in. with_tz defaults to the Universal Coordinated time zone (UTC) when an unrecognized time zone is inputted. See Sys.timezone() for more information on how R recognizes time zones.
