Define custom date formats

Define custom date formats to control how date data is presented in Sigma.

When you enter a custom format string, you can use the supported date formats independently or in combination with other formats and characters, including letters, numbers, and symbols.


Custom format strings applied to the value "2019-02-10 15:22:23" return the following output:

Format stringOutput
%a, %b %d, %YSun, Feb 10, 2019
%I:%M:%S %p03:22:23 PM


When applying the DateFormat and DateParse functions, date formatting occurs in your CDW/DBMS, which may not support the date formats described in this document.
