*1 The time expressed as the number of seconds from 00:00:00 on January 1st, 1970.
(For example, if the date/time is 00:00:00 on January 1st, 2015, the value is 1,420,070,400 seconds.)
*2 The upper and lower data registers change according to the 32-bit data storage method specified. For details, see Chapter 3 "Instructions
Reference" - "32-bit Data Storage" on page 3-9.
