datetime.new()

datetime.new([{ units }])¶

Since 2.10.0.

Create an object of the datetime type from a table of time units. See description of units and examples below.

Параметры:	units (table) – Table of time units. If an empty table or no arguments are passed, the datetime object with the default values corresponding to Unix Epoch is created: 1970-01-01T00:00:00Z.
Return:	datetime object
Rtype:	cdata

Possible input time units for ``datetime.new()``

Name	Description	Type	Default
nsec (usec, msec)	Fractional part of the last second. You can specify either nanoseconds (nsec), or microseconds (usec), or milliseconds (msec). Specifying two of these units simultaneously or all three ones lead to an error.	number	0
sec	Seconds. Value range: 0 - 60.	number	0
min	Minutes. Value range: 0 - 59.	number	0
hour	Hours. Value range: 0 - 23.	number	0
day	Day number. Value range: 1 - 31. The special value -1 generates the last day of a particular month (see example below).	number	1
month	Month number. Value range: 1 - 12.	number	1
year	Year.	number	1970
timestamp	Timestamp, in seconds. Similar to the Unix timestamp, but can have a fractional part which is converted in nanoseconds in the resulting datetime object. If the fractional part for the last second is set via the nsec, usec, or msec units, the timestamp value should be integer otherwise an error occurs. Timestamp is not allowed if you already set time and/or date via specific units, namely, sec, min, hour, day, month, and year.	number	0
tzoffset	Time zone offset from UTC, in minutes. If both tzoffset and tz are specified, tz has the preference and the tzoffset value is ignored.	number	0
tz	Time zone name according to the tz database.	string

Examples:

tarantool> datetime.new {

            sec = 20,
            min = 25,
            hour = 18,

            day = 20,
            month = 8,
            year = 2021,

            tzoffset  = 180
