Required methods

Format Date with a fmt rule. See chrono strftime/strptime.

Extract hour from underlying NaiveDateTime representation. Returns the hour number from 0 to 23.

Extract minute from underlying NaiveDateTime representation. Returns the minute number from 0 to 59.

Extract second from underlying NaiveDateTime representation. Returns the second number from 0 to 59.

Extract second from underlying NaiveDateTime representation. Returns the number of nanoseconds since the whole non-leap second. The range from 1,000,000,000 to 1,999,999,999 represents the leap second.
