pub struct TimeTime { /* private fields */ }Expand description
The clock time within a given date. Nanosecond precision.
All minutes are assumed to have exactly 60 seconds; no attempt is made to handle leap seconds (either positive or negative).
When comparing two Times, they are assumed to be in the same calendar date.
