date date
Required

Datetime object (100AD-9999AD).

timezone timezone
Default: Timezone Specified in Lucee Administrator

This is only available in Lucee.
A datetime object is independent of a specific timezone; it is only an offset in milliseconds from 1970-1-1 00.00:00 UTC.
The timezone only comes into play when you need specific information like hours in a day, minutes in an hour or which day it is, as these calculations depend on the timezone.
A timezone must be specified in order to translate the date object to something else. If you do not provide the timezone in the function call, it will default to the timezone specified in the Lucee Administrator (Settings/Regional), or the timezone specified for the current request using the function setTimezone().
