Module Core_kernel__.Zone_intf

module type Time_in_seconds = sig ... end

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.

module type S = sig ... end

This is the interface of Zone, but not the interface of Time.Zone or Time_ns.Zone. For those, look at Time_intf.Zone

module type S_stable = sig ... end
module type Zone = sig ... end
