How to set User Preference for Timezone for bulk user?

[ACDD]

Only ITIL and Admin users are able to select the timezone from preferences. How to set timezone for rest required users ? Is there any way to create a record on User Preferences table for this requirement?

Hi @ACDD ,

I have had a look into it but I cannot see any way to use the user preference table to do this.

Thanks
