Details and Options Details and Options

DateList[] uses whatever date and time have been set on your computer system. It performs no corrections for time zones, daylight saving time, etc.
DateList[TimeZone->z] gives the date and time inferred for time zone z by assuming that your computer is set for the time zone specified by $TimeZone. »
All values returned by DateList[] are integers, except the number of seconds. The number of seconds is never more accurate than $TimeUnit.
Shorter lists can be used in DateList[{y,m,…}]: {y} is equivalent to {y,1,1,0,0,0}, {y,m} to {y,m,1,0,0,0}, etc.
Values of m, d, h, m, s outside their normal ranges are appropriately reduced. Noninteger values of d, h, m, s can also be used. »
You can compare two lists returned by DateList using Order. »
In the form DateList[{"string",{"e₁","e₂",…}}], the "e_i" can be "Year", "YearShort", "Quarter", "Month", "MonthName", "Day", "DayName", "Hour", "Hour12", "AMPM", "Minute", "Second", or "Millisecond".
DateList[{"string",{"e₁","e₂",…}}] uses the "e_i" to fill in elements of {y,m,d,h,m,s}. Those not filled in are taken to have default values {y_c,1,1,0,0,0}, where y_c is the current year. »
In DateList[{"string",{"e₁","e₂",…}}], the "e_i" are extracted from "string" in the order given, and can be separated by any non-alphanumeric characters. »
DateList[{"string",{"e₁","sep₁₂","e₂","sep₂₃",…}}] extracts elements using the explicit separators specified. »
