Converts a UTC or GMT timestamp to local time as a dual value. The place can be any of a number of cities, places and time zones around the world.
Syntax:
ConvertToLocalTime(timestamp [, place [, ignore_dst=false]])
Return data type: dual
| Argument | Description |
|---|---|
| timestamp | The timestamp, or expression resolving to a timestamp, to convert. |
| place |
A place or timezone from the table of valid places and timezones below. Alternatively, you can use GMT or UTC to define the local time. The following values and time offset ranges are valid:
Information noteIf you use a DST offset (that is, you specify an ignore_dst argument value evaluating to False), you must specify a place, rather than a GMT offset, in the place argument. This is because adjusting for Daylight Saving Time requires latitudinal information in addition to the longitudinal information provided by a GMT offset. For information, see Using GMT offsets in combination with DST.
Information noteYou can only use standard time offsets. It's not possible to use an arbitrary time offset, for example, GMT-04:27.

| ignore_dst |
If this argument evaluates to True, DST (daylight saving time) is ignored. Valid argument values evaluating to True include -1 and True(). If this argument evaluates to False, the timestamp is adjusted for daylight saving time. Valid argument values evaluating to False include 0 and False(). If the ignore_dst argument value is invalid, the function evaluates the expression as if the ignore_dst value evaluates to True. If the ignore_dst argument value is not specified, the function evaluates the expression as if the ignore_dst value evaluates to False. |

Using GMT offsets in combination with DST
Following the implementation of International Components for Unicode (ICU) libraries in Qlik Sense, the use of GMT (Greenwich Mean Time) offsets in combination with DST (Daylight Saving Time) requires additional latitudinal information.
GMT is a longitudinal (east-west) offset, whereas DST is a latitudinal (north-south) offset. For example, Helsinki (Finland) and Johannesburg (South Africa) share the same GMT+02:00 offset, but they do not share the same DST offset. This means that, further to the GMT offset, any DST offset requires information on the latitudinal position of the local time zone (geographical time zone input) in order to have full information about local DST conditions.
