UNIXTIMEFORMAT Function

Formats a set of Unix timestamps according to a specified date formatting string.

Source values can be a reference to a column containing Unix timestamp values.

注記

Date values must be converted to Unix timestamps before applying this function. Unix time measures the number of milliseconds that have elapsed since January 1, 1970 00:00:00 (UTC). See UNIXTIME Function.

Supported format strings for this function are the same as the supported format strings for the DATEFORMAT function.

Wrangle vs. SQL: This function is part of Wrangle, a proprietary data transformation language. Wrangle is not SQL. For more information, see Wrangle Language.
