UI

Name	DescriptionScreen (Click to view)
Placeholder	The placeholder attribute specifies a short hint that describes the expected value of an input field (e.g. a sample value or a short description of the expected format). The short hint is displayed in the input field before the user enters a value.
Display Format	The Display Format uses the jQuery date syntax. For example, the yy-M-dd displays as 2019-10-23. Reference: https://github.com/phstc/jquery-dateFormat When this field is left empty, the following will be considered. If current locale starts with "zh", the format will be set as "yy-mm-dd". If "Using Locate Date Format" is set in General Settings, date format based on current user's locale will be used. Otherwise, it will use "M/dd/yy".
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). Code Block title Sample - Show 10 years before and after c-10:c+10 Code Block title Sample - Show specific year range 2000:2020
Readonly	Determines if the element is editable.
Display field as Label when readonly?	Displays the value of the element as plain text when element is set to "Readonly".

Date Formatting Based On Locale

...

1. In System Settings:
   1. Tick the checkbox `Using Locale Date Format`.
   2. Leave the `System Date Format` field blank or empty.
   3. Tick the checkbox `Enable User Locale Selection`.
   4. Enter into the 'User Locale Options' field the locales allowed, for example "de,en_US".
   5. Save the System Settings.
2. In your "Form Builder > Date Picker", leave the 'Display Format' property blank or empty.
3. 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:

set JAVA_OPTS=-Xmx2048M -Dwflow.home=./wflow/ -javaagent:./wflow/aspectjweaver-1.8.5.jar -Duser.timezone=UTC -javaagent:./wflow/glowroot/glowroot.jar
