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.
