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
Although the new date-time has the same clock time (e.g. the

different moment of time than the input date-time. force_tz defaults to the

Sys.timezone for more information on how R
recognizes time zones.

- a POSIXct, POSIXlt, Date, chron date-time object, or a data.frame

force_tzand new data.frame is returned.
- 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.
