Represents a date and time of day with an offset from UTC in the ISO 8601 calendar system.
IMPORTANT: This is an early preview release available for testing and feedback. The API is still subject to change.
$tm = Time::Moment->now;
Constructs an instance of Time::Moment that is set to the current date and time from the system clock in the system time zone, with the offset set to the system's time zone offset from UTC.
Time::Moment
$tm = Time::Moment->now_utc;
Constructs an instance of Time::Moment that is set to the current date and time from the system clock in the UTC time zone.
$tm = Time::Moment->from_epoch($seconds); $tm = Time::Moment->from_epoch($seconds, $nanosecond); $tm = Time::Moment->from_epoch($seconds, $nanosecond, $offset);
Constructs an instance of Time::Moment from the given seconds from the epoch of 1970-01-01T00:00:00Z. The optional parameter nanosecond specifies the nanosecond [0, 999_999_999]. The optional parameter offset specifies the time zone offset from UTC in minutes [-1080, 1080].
$tm = Time::Moment->from_object($object);
Constructs an instance of Time::Moment from the given object. If the given object is an instance of Time::Moment it's returned otherwise an attempt is made to coerce the given object to an instance of Time::Moment.
Time::Moment provides coercion handlers for the following object types:
$tm = Time::Moment->from_object( DateTime->now ); $tm = Params::Coerce::coerce('Time::Moment', DateTime->now);
The given DateTime object must be within the supported date range and must have a time zone or a time zone offset from UTC, coercing from the 'floating' time zone is not supported.
DateTime
$tm = Time::Moment->from_object( Time::Piece::localtime() ); $tm = Params::Coerce::coerce('Time::Moment', Time::Piece::localtime());
The given Time::Piece object must be within the supported date range.
Time::Piece
The coercion scheme is extensible and implemented as documented in Params::Coerce.
$tm = Time::Moment->from_string($string);
Constructs an instance of Time::Moment from the given string. The string must consist of a complete representation of a date and time of day followed by a zone designator. The second part of the time of day representation may have a decimal fraction.
The following are examples of complete representations of date and time of day representations:
Basic format: Example: YYYYMMDDThhmmssZ 20121224T121530Z YYYYMMDDThhmmss±hhmm 20121224T121530+0100 YYYYMMDDThhmmss±hh 20121224T121530+01 Extended format: Example: YYYY-MM-DDThh:mm:ssZ 2012-12-24T12:15:30Z YYYY-MM-DDThh:mm:ss±hh:mm 2012-12-24T12:15:30+01:00 YYYY-MM-DDThh:mm:ss±hh 2012-12-24T12:15:30+01
