Time! datatype
1. Abstract
Time!
values represent an amount of time, specified in hours, minutes, and seconds. They may be interpreted as an offset from midnight, in the context of dates, or as absolute times of day.
Time!
is a member of the following typesets: immediate!
, scalar!
2. Creation
Time!
values can be created using literal syntax, or at runtime by using a make
constructor or to
conversion.
3. Literal syntax
4. Runtime Creation
make time! [<hour> <minute> <second>] make time! <integerliteral>  <floatliteral> to time! [<hour> <minute> <second>] to time! <integerliteral>  <floatliteral> <hour> : <integerliteral> <minute> : <integerliteral> <second> : <integerliteral>  <floatliteral>
>> make time! 60
== 0:01:00
>> make time! 95'000
== 26:23:20
>> make time! [3 2 1]
== 3:02:01
>> make time! 300.45
== 0:05:00.45
>> to time! 60
== 0:01:00
>> to time! 95'000
== 26:23:20
>> to time! [3 2 1]
== 3:02:01
5. Path accessors
Path accessors provide a convenient way for getting and setting all time!
value fields.
5.1. /hour
Description
Gets or sets the hour field of a time. Hour is returned as an integer!
value.
Examples
>> t: make time! [3 2 1]
== 3:02:01
>> t/hour
== 3
>> t/hour: 6
== 6
>> t
== 6:02:01
5.2. /minute
Description
Gets or sets the minute field of a time. Minute is returned as an integer!
value.
Examples
>> t: make time! [3 2 1]
== 3:02:01
>> t/minute
== 2
>> t/minute: 7
== 7
>> t
== 3:07:01
5.3. /second
Description
Gets or sets the second field of a time. Second is returned as an float!
value.
Examples
>> t: make time! [3 2 1]
== 3:02:01
>> t/second
== 1.0
>> t/second: 58
== 58
>> t
== 3:02:58
Time fields are also accessible by index using path notation.
>> t
== 3:02:01
>> t/1
== 3
>> t/2
== 2
>> t/3
== 1.0
5.4. Accessing time fields using Pick
It is possible to access time fields without using a path, which can be more convenient in some cases. pick
can be used for that on times.
Syntax
pick <time> <field> <time> : a time! value <field> : an integer! value
Examples
>> t
== 3:02:01
>> pick t 1
== 3
>> pick t 2
== 2
>> pick t 3
== 1.0
6. Conversions
to integer! <time> <time> : a time! value
>> t
== 3:02:01
>> to integer! t
== 10921
to float! <time> <time> : a time! value
>> t
== 3:02:01
>> to float! t
== 10921.0
Integer!
, float!
, and percent!
values can be converted to time.
>> i: to integer! t
== 10921
>> to time! i
== 3:02:01
>> f: to float! t
== 10921.0
>> to time! f
== 3:02:01
>> p: to percent! t
== 1092100%
>> to time! p
== 3:02:01
7. Comparisons
All comparators can be applied on time!
: =, ==, <>, >, <, >=, <=, =?
. In addition, min
, and max
are also supported.
8. Arithmetic
Supported math operations on times include:

adding or subtracting values from any time field.

adding or subtracting an integer value with a time value.

adding or subtracting a time value with a time value.

multiplying or dividing values from any time field.

multiplying or dividing an integer value with a time value.
Examples
>> t: 2:30:45
== 2:30:45
>> t/hour: t/hour + 5
== 7
>> t
== 7:30:45
>> t/minute: t/minute  20
== 10
>> t
== 7:10:45
>> 1:40:45 + 50
== 1:41:35
>> 1:40:45  100
== 1:39:05
>> 3:02:01 + 1:45:30
== 4:47:31
>> 3:02:01  1:00:00
== 2:02:01
t: 2:30:45
>> t/second: t/second * 5
== 225.0
>> t
== 2:33:45
>> t/2 / 3
== 11
>> t/2 // 3
== 0
>> t/3 * 3
== 135.0
9. Testing values
Use time?
to check if a value is of the time!
datatype.
>> time? t
== true
Use type?
to return the datatype of a given value.
>> type? t
== time!
>>
