mscTimeOffset 1.3.6.1.4.1.562.36.2.1.19.10.1.6

This attribute specifies the number of minutes to be added to the reference time, which is Universal Coordinated Time (UTC), to obtain the moduleTime. It keeps its value even if the card boots. However, if the node is powered-off for more than 24 hours, it resets to the default value, which is 0. The specified value should be in the range -720 (-12 hours) to 720 (+12 hours). Values greater than 720 are accepted for backward compatibility; for example, 780 (13 hours) corresponds to an offset of -11 hours. If a value greater than 720 is entered, it will be displayed as a negative offset.
