This attribute indicates the current date and time on this module.
The moduleTime is obtained by adding an offset to the reference
time, which is the Universal Time Coordinated (UTC). When the
moduleTime is set, it keeps the value even if the card boots. It is the
time used for time stamps, such as in alarms and accounting data.
The operator resets the current date and time by setting this attribute
when syncStatus is unsynchronized. Setting this attribute is not
allowed if syncStatus is synchronized or synchronizing.
