Qlik Application Automation has a "convert timezone" block that allows you to convert a given time from one timezone to another. This article explains how this block should be used.
In some use-cases, you want to ask a user to enter her timezone as a parameter in an inputs block. To do this you could use a dropdown that you populate with possible timezones. Use the "List timezones" formula in combination with the "implode" formula to populate the dropdown's options field.
The unparsed formula looks like this: {implode: '{listtimezones}', ','}
Then you can use the timezone the user selected in the "convert timezone" formula. The following example will convert a 13:00:00 time in timezone 'Europe/Brussels' to a time in a timezone specified by the user.
