Hi Team,
I have a table with GQIDatetimeColumn as Service Start Dt & Service End Dt both of these columns are of UTC time.
On selecting the alarms icon on a panel i will show Time Range component which has default value of Start & End as the selected value. I have done this using the custom option in Time Range component.
Now on the Time Range is always showing time as time zone I am in for eg. CIEC India i.e +5hrs 30min ahead of the Start & End value in table.
In our table we have time in UTC, so we also wanted when we see the time range in the component that should be UTC too, but it takes system time.
As what happens although its system time when goes via script its UTC, so functionality works fine but its misleading as time in timerange component is system time. 
Hi Apurva,
I believe this is the setting you are looking for Default time zone.
The value for UTC should be this:
{
"Name": "commonServer.ui.DefaultTimeZone",
"Value": "UTC;0;(UTC) Co-ordinated Universal Time;Co-ordinated Universal Time;Co-ordinated Universal Time;;",
"VersionNumber": 0,
"Mode": 0,
"InVisible": false
},
This will override the timezone that is used in the WebApps for all users.
Kind regards,
Robin
