Thank you, Haley Won, for a great Quick Tip, "User Profile and Browser Time Zones are Always in Sync"
Beginning with Sugar 12.3, you no longer have to worry about discrepancies in time zones, as your user profile time zone in Sugar will automatically be updated to match the browser’s time zone!
As a side note, the Time Zone setting in your user profile will no longer be editable as it's read-only.
