module Period: sig
.. end
A period is the number of seconds between two times.
Arithmetic operations
include Period.S
val length : [< Period.date_field ] period -> Time_sig.S.second
Number of seconds of a period.
val mul : ([< Period.date_field ] as 'a) period -> 'a period -> 'a period
Multiplication.
val div : ([< Period.date_field ] as 'a) period -> 'a period -> 'a period
Division.
Constructors
val make : int -> int -> Time_sig.S.second -> [< Period.date_field ] period
make hour minute second
makes a period of the specified length.
val lmake : ?hour:int ->
?minute:int ->
?second:Time_sig.S.second -> unit -> [< Period.date_field ] period
Labelled version of make
.
The default value is 0
for each argument.
val hour : int -> [< Period.date_field ] period
hour n
makes a period of n
hours.
val minute : int -> [< Period.date_field ] period
minute n
makes a period of n
minutes.
val second : Time_sig.S.second -> [< Period.date_field ] period
second n
makes a period of n
seconds.
Getters
val to_seconds : [< Period.date_field ] period -> Time_sig.S.second
Number of seconds of a period.
Since 1.04
Example: to_seconds (make 1 2 3)
returns 3600 + 120 + 3 = 3723
.
val to_minutes : [< Period.date_field ] period -> float
Number of minutes of a period. The resulting fractional part
represents seconds.
Since 1.04
Example: to_minutes (make 1 2 3)
returns 60 + 2 + 0.05 = 62.05
.
val to_hours : [< Period.date_field ] period -> float
Number of hours of a period. The resulting fractional part represents
minutes and seconds.
Since 1.04
Example: to_hours (make 1 3 0)
returns 1 + 0.05 = 1.05
