Detailed Description

A timestamp with nanosecond resolution.

Note: If the structure is to represent a negative value then both the fields nano_secs and secs have to be set to the negative values. Otherwise the sign of the represented number was ambiguous if either of the fields was accidentally 0, and only the other field was not 0. The macro _nano_time_negative should always be used to determine if the sign of the represented value is negative, or not.; The secs field will roll over on 2038-01-19 03:14:07 if used for the number of seconds since 1970-01-01, just like 32 bit POSIX time_t.
