Replace time zone to create new date-time
force_tz returns a the date-time that has the same clock
time as x in the new time zone. Although the new
date-time has the same clock time (e.g. the same values
in the year, month, days, etc. elements) it is a
different moment of time than the input date-time.
force_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.
force_tz(time, tzone = "")
- a POSIXct, POSIXlt, Date, or chron date-time object.
- a character string containing the time zone to convert to. R must recognize the name contained in the string as a time zone on your system.
- a POSIXct object in the updated time zone
x <- as.POSIXct("2009-08-07 00:00:01", tz = "America/New_york") force_tz(x, "GMT") # "2009-08-07 00:00:01 GMT"
