Precedence for DATETIME display formats
The DATETIME-format functions use a precedence to determine the display format of values in DATETIME columns.
The precedence is as follows:
- The display format that DBTIME specifies (if DBTIME is set)
- The display format that GL_DATETIME specifies (if GL_DATETIME is set)
- The date and time display formats that the client locale specifies (if CLIENT_LOCALE is set)
- The date and time display format from the default locale: %iY-%m-%d %H:%M:%S
