TOD fields

All field in TOD format contain the time-of-day clock value and are set automatically from the system when a replace or insert request is issued. This data is represented in a binary counter corresponding to a 64-bits unsigned integer and its value is implemented every 2-12 microseconds (clock unit) starting from 1st January 1900 with the cycle of the clock of approximately 143 years. In order to understand better the content of this field, please refer to the two tables below:
