| Date Picker Year Range | Range of years to be shown In essence, the value left of the colon ":" must be a negative number and on the right must be a positive number. It indicates to Joget Workflow how many years earlier and how many years forward to display in the year select box based on the selected year. A value of "c-0:c+0" is also valid, this indicates to the user that he cannot change the year value (it will default to the current system year).

Date Formatting Based On Locale
Here are the steps to set the Date Picker to automatically display the date format based on user locale ( for example ""MM/dd/yyyy" for "en_US" locale ):
- In System Settings:
- Tick the checkbox `Using Locale Date Format`.
- Leave the `System Date Format` field blank or empty.
- Tick the checkbox `Enable User Locale Selection`.
- Enter into the 'User Locale Options' field the locales allowed, for example "de,en_US".
- Save the System Settings.
- In your "Form Builder > Date Picker", leave the 'Display Format' property blank or empty.
- User logs in, sets his locale in 'My Profile'. Date Picker field will show the date format as per his/her locale.
Display Date Time Based On Coordinated Universal Time (UTC)
You can 'force' Joget to generate the date time from the data hash variable based on UTC, by adding the parameter "-Duser.timezone=UTC" in the JAVA_OPTS variable in the Joget startup script/batch file:
| Code Block | ||
|---|---|---|
| ||
set JAVA_OPTS=-Xmx2048M -Dwflow.home=./wflow/ -javaagent:./wflow/aspectjweaver-1.8.5.jar -Duser.timezone=UTC -javaagent:./wflow/glowroot/glowroot.jar |
