Using the below query we are able to get TimeZone:
SELECT ID, TimeZoneSidKey FROM User WHERE ID = :UserInfo.getUserId()
For example, on edit user detail, if we pick the Time zone as (GMT-08:00) Pacific Standard Time (America/Los_Angeles) from the pick list then the TimeZoneSidKey will be America/Los_Angeles.
Is there any method to get the TimeZoneSidKey's value i.e, (GMT-08:00) Pacific Standard Time (America/Los_Angeles) ?
Can anyone help me out with suggestions on how can i customize the approval history buttons.
I have a requirement where once the record has finished the stages of approval the submit for approval button should be disabled. Also how can i customize the Approve/Reject buttons.
