Date functions

The Date functions provide methods for creating Date values, calculating new Dates, getting various properties of Dates, and changing a Date's display properties.

ChangeTimeZone

ChangeTimeZone(dateValue, newTimeZone) -> Date

Since version 1.24

Function bundle: Core

Changes the time zone used to display the given Date value. If the input dateValue has an unknown time zone, then the output Date value will display with the same date and time as the input dateValue, but will be assigned the newTimeZone.

Parameters

• dateValue: Date - A Date value containing date and time information.

• newTimeZone: Text - The new time zone that will be used to display the given Date value. The time zone must be one of the following:

  • text representing an entry in the IANA time zone database (e.g. America/New_York)

  • text representing the hours and minutes that should be added to UTC (e.g. +07:00 or -03:00)

  • system - time zone will be set to the device or system's local time zone

  • default - the time zone of the profile's execution context

  • UTC - Coordinated Universal Time

  • unknown - removes time zone information for the given value and displays the date and time as defined in the expression.

Return value: Date

Additional resources

• IANA time zone database
• Arcade execution context
• ToLocal()
