DateTime Format

The Rendezvous datatype TIBRVMSG_DATETIME indicates a value in DateTime format.

Rendezvous DateTime format encodes the time with microsecond accuracy. The total time range is approximately 17432 years on each side of the epoch (midnight, zero seconds into January 1, 1970).

In wire format, DateTime values are 8 bytes:

•	40 signed bits representing seconds (zero denotes the UNIX epoch, namely, 12:00am, January 1, 1970).

•	24 unsigned bits representing microseconds after the seconds value.

 

Although the program representations of DateTime values can be significantly larger than these 64 bits, the excess is unused at this time.
