module Zone : Zone with module Time := Time
Basic operations on times
val add : t -> Span.t -> t

add t s adds the span s to time t and returns the resulting time.

NOTE: adding spans as a means of adding days is not accurate, and may run into trouble due to shifts in daylight savings time, float arithmetic issues, and leap seconds. See the comment at the top of Zone.mli for a more complete discussion of some of the issues of time-keeping. For spans that cross date boundaries, use date functions instead.

val sub : t -> Span.t -> t

sub t s subtracts the span s from time t and returns the resulting time. See important note for add.

val diff : t -> t -> Span.t

diff t1 t2 returns time t1 minus time t2.

val abs_diff : t -> t -> Span.t

abs_diff t1 t2 returns the absolute span of time t1 minus time t2.
