Seems a misguided practice to me.<p>* Store datetime values in UTC. Else you get inconsistent values, which has unpredictable consequences.<p>* Detect user&#x27;s expected timezone using one of : a) user preference setting, b) the region the app is supposed to be running for, c) IP geolocation. Choice depends on the app requirements. Don&#x27;t default to any timezone unless considered 100% safe.<p>* Present DB values in the UI using said detected timezone.<p>* UI-wise, slways display timezone information for datetime values. At the very least in a tooltip.
