timeConvert
Convert from one time zone to another.

Description

Converts a time/date object from one time zone to another.

Usage

timeConvert(x, to.zone, from.zone)

Arguments

x the time/date object to convert.
to.zone the time zone to convert to (character).
from.zone the time zone to convert from (character). For timeDate objects, this is ignored. Instead, the value is taken from the time.zone slot of the timeDate object.

Details

The timeDate stores times/dates as their equivalent time in GMT, with a time zone (used for printing and other operations) stored in the time.zone slot. Therefore, to convert time zones, this function simply puts the new time zone into the time.zone slot.
Value
returns the time/date object reflecting the converted time zone.
