Date: Utility methods

Sometimes you need to convert a Date Object into a formatted stream, for example to display a date on a grid or a detail form.
Displaying a date without formatting will show the Javascript representation of a string, which is something like:
Wed Jul 06 2016 09:47:04 GMT+0200 (CEST)
To convert this into a more readable string like
Wednesday, 06 July 2016 09:47:04
The following utility function can be used
var datestr = utils.convertDateToString(date_from_filter, 'dd/MM/yyyy HH:mm:ss');
The format parameter is made up similarly to Java:

Add a value to Date:
  • newDate = utils.addDate(Long currentTimeMillis, String field, int amount)
  • newDate = utils.addDate(String field, int amount): lo aggiunge alla data attuale
  • newDate = utils.addDate(String date, String format, String field, int amount)
