Note about terminal clock deviation
The message send through IP and RS485 includes the date/time of access control
result. The terminal clock has a +/- 4 sec per day typical time deviation at +25°C.
At 50°C, the time deviation may be up to -8 sec per day.
For features that requiring time precision (such as SSL protocol or DESFire™
contactless card), the clock of the MorphoAccess® terminal must be synchronized
regularly with an external clock (using the appropriated ILV command).
