A plain_time() is a time of day with nanosecond precision and no date
or time zone, stored as a double count of nanoseconds since midnight.
The constructor is Temporal.PlainTime and
Temporal.PlainTime.from() in one: it reads fields, strings or another
zutempo value.
Usage
plain_time(
hour = 0,
minute = 0,
second = 0,
millisecond = 0,
microsecond = 0,
nanosecond = 0,
...,
overflow = "constrain"
)
plain_time_compare(x, y)Arguments
- hour
The hour (0 to 23), or a string in ISO 8601 form (
"12:30","12:30:45.123456789","T12", or a date-time whose date is ignored; a bare time that could also read as a month-day or year-month must carry theTprefix), or aplain_time(),plain_date_time()orzoned_date_time()to convert, or adifftimefrom 0 up to 24 hours after midnight.- minute, second, millisecond, microsecond, nanosecond
The remaining fields, 0 by default.
- ...
Must be empty.
- overflow
"constrain"(the default) clamps each field to its range,"reject"raises azutempo_range_error.- x, y
plain_time()values or strings, forplain_time_compare().
Members
Every member of Temporal.PlainTime in the pinned specification
(inst/spec/PINS) and the R function that implements it:
| Temporal | R |
new Temporal.PlainTime() | plain_time() |
Temporal.PlainTime.from() | plain_time() |
Temporal.PlainTime.compare() | plain_time_compare() |
.hour | hour() |
.minute | minute() |
.second | second() |
.millisecond | millisecond() |
.microsecond | microsecond() |
.nanosecond | nanosecond() |
.add() | temporal_add() |

.since() | temporal_since() |
.round() | temporal_round() |
.equals() | temporal_equals() |
.toString() | temporal_to_string() |
.toLocaleString() | none: ECMA-402 (locale formatting) is out of scope |
.toJSON() | none: format() covers it |
.valueOf() | none: throws in JavaScript; no R counterpart |
