Struct saphir::cookie::time::Time

pub struct Time { /* private fields */ }

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.
