cDateList

The output of DateList is always a list of six elements (either 5 integers + 1 real or 6 integers).

Current DateList with default TimeZone:

cDateList[]

(* Out: {2022, 1, 16, 19, 49, 47.} *)

Current DateList with custom TimeZone:

cDateList[TimeZone -> 2]

(* Out: {2022, 1, 16, 18, 19, 47.} *)

Convert offset in second from 1900-1-1 to DateList with Default TimeZone:

cDateList[123456789]

(* Out: {1903, 11, 30, 21, 33, 9.} *)

Convert offset in second from 1900-1-1 to DateList with custom TimeZone:

cDateList[{2021, 2, 3}, TimeZone -> 2]

(* Out: {1903, 11, 30, 20, 3, 9.} *)

Get full length DateList:

cDateList[{2021, 2, 3}]
(* Out: {2021, 2, 3, 0, 0, 0.} *)

cDateList[{2021, 2, 3}, TimeZone -> 2]
(* Out: {2021, 2, 2, 22, 30, 0.} *)

Correct numbers:

cDateList[{2021, 2, -1}]

(* Out: {2021, 1, 30, 0, 0, 0.} *)

Convert from other calendars to "Gregorian":

cDateList[DateObject[{1404, 1, 1}, CalendarType -> "ArithmeticPersian"]]

(* Out: {2025, 3, 20, 0, 0, 0.} *)

Convert from other calendars to "Gregorian" with custom Method:

cDateList[DateObject[{1404, 1, 1}, CalendarType -> "ArithmeticPersian"], Method -> "Cycle-2820-2"]

(* Out: {2025, 3, 21, 0, 0, 0.} *)
