TODAY() and NOW() formulas value coming from device date and time

TODAY() and NOW() formulas value coming from device date and time!!!

Is there anyway to connect and get date and time from international or server?

Dear Team

Please help on it. becuase I made Timesheet app here. now users making fake time in-out using this bad way.

UTCNOW() - AppSheet Help

USERTZOFFSET() - AppSheet Help

Dieses Thema wird schon lange diskutiert, siehe Zeitstempelmanipulation verhindern

NOW()

UTCNOW()

There is not difference. Still I can manipulate UTC time by changing device time.

Still there is no solution!!!
