Struct rustdds::dds::data_types::DDSTimestamp [−][src]
pub struct DDSTimestamp { /* fields omitted */ }
Expand description
Quoting RTPS 2.3 spec 9.3.2.1:
The representation of the time is the one defined by the IETF Network Time Protocol (NTP) Standard (IETF RFC 1305). In this representation, time is expressed in seconds and fraction of seconds using the formula: time = seconds + (fraction / 2^(32))
The time origin is represented by the reserved value TIME_ZERO and corresponds to the UNIX prime epoch 0h, 1 January 1970.
Note : NTP does not use the Unix epoch (1970-01-01 00:00) but the beginning of the 20th century epoch (1900-01-01 00:00) insted. So these timestamps are not the same as in NTP. This time representation is used in RTPS messages. This is called Time_t in the RTPS spec.
