R: Get date-time in a different time zone

with_tz {lubridate} | R Documentation

## Get date-time in a different time zone

### Description

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.

### Usage

    with_tz(time, tzone = "")

### Arguments

`time` | a POSIXct, POSIXlt, Date, chron date-time object or a data.frame object. When a data.frame all POSIXt elements of a data.frame are processed with `with_tz()` and new data.frame is returned.
`tzone` | 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.

### Value

a POSIXct object in the updated time zone

`force_tz()`

### Examples

    x <- ymd_hms("2009-08-07 00:00:01", tz = "America/New_York")
    with_tz(x, "GMT")
