utc

        # Time.utc

(from ruby core)
---
    Time.utc(year, month=1, day=1, hour=0, min=0, sec_i=0, usec=0) -> new_time
    Time.utc(sec_i, min, hour, day, month, year, dummy, dummy, dummy, dummy) -> new_time

---

Returns a new Time object based the on given arguments; its timezone is
UTC.

In the first form (up to seven arguments), argument `year` is required.

    Time.utc(2000)                  # => 2000-01-01 00:00:00 UTC
    Time.utc(0, 1, 2, 3, 4, 5, 6.5) # => 0000-01-02 03:04:05.0000065 UTC

In the second form, all ten arguments are required, though the last four
are ignored. This form is useful for creating a time from a 10-element
array such as is returned by #to_a.

    array = Time.now.to_a
    p array # => [57, 26, 13, 24, 4, 2021, 6, 114, true, "Central Daylight Time"]
    array[5] = 2000
    Time.utc(*array) # => 2000-04-24 13:26:57 UTC

Parameters:
*   `year`: an integer year.
*   `month`: a month value, which may be:
    *   An integer month in the range `1..12`.
    *   A 3-character string that matches regular expression
        `/jan|feb|mar|apr|may|jun|jul|aug|sep|oct|nov|dec/i`.

*   `day`: an integer day in the range `1..31` (less than 31 for some
    months).
*   `hour`: an integer hour in the range `0..23`.
*   `min`: an integer minute in the range `0..59`.
*   `isec_i` is the integer number of seconds in the range `0..60`.
*   `usec` is the number of microseconds (Integer, Float, or Rational)
    in the range `0..1000000`.
