Timestamp format records seconds as 2 seconds intervals, so 10ms increments are used to increase precision from 2 seconds to 10 milliseconds.

The valid values are from 0 to 199 in 10ms intervals which are added to correspondent timestamp. Timestamp is recorded in local time. Time zone offset is expressed in 15 minutes increments.
