Module type `Zone_intf.Time_in_seconds`

The internal time representation of Zone.t. This is a tiny subset of Time0_intf.S, see that interface for details such as the meaning of Span and Date_and_ofday.

The name of the interface reflects the fact that the interface only gives you access to the seconds of the t. But you can use this interface with types that have higher precision than that, hence the rounding implied in the name of to_int63_seconds_round_down_exn.
