Ok, I got the Time Zone conversion working. That was easy.
Can someone help with how to convert a SP List 'Start Time' text column record (in 24h time) to the new time when a user selects a Time Zone from a Gallery?
Example 1:
If SP column 'Start Time' is 10:00 (based on UTC-6:00) and the user selected their time zone from TimeZone Gallery.item (UTC-5:00) Eastern Time (US and Canada), how can I show a text label of the converted time to 11:00?
Example 2:
If SP column 'Start Time' is 11:00 (based on UTC-3:00) and the user selected their time zone from TimeZone Gallery.item (UTC+9:00) Osaka,Saporro, Tokyo, how can I show a text label of the converted time to 23:00?
The Time Zone Gallery item selections from a SP List choice column are formatted as follows:
