Show actual time

[yeungyam]

I am not sure if it is possible, I have a field that shows the time when the form was opened with the usual code:

 var c = this.getField("TimeStamp");
c.value = util.printd ("HH:MM", new Date());

But I would like the time to change as time goes on. The user could have opened the form at 10:00, but took 20 minutes to fill the form, so I would like to see the 10:20 time shown.

Is there a way to see the actual time in a field?

Sure. You'd use the app.setInterval method. The code that it calls would be the same as you showed, but it easily be condensed to a single line. More information here: https://help.adobe.com/en_US/acrobat/acrobat_dc_sdk/2015/HTMLHelp/#t=Acro12_MasterBook%2FJS_API_Acro...

This worked well on the desktop.

However on iPad it doesn't work, but it might be due to a limitation on the iPad, otherwise it works.

I don't think it's a good idea to do a timer that goes on constantly, at least not for the purpose you mentioned. Why not just update the "TimeStamp" field when the file is saved, for example? You can use the Will Save document event to do it.

I know this would make more sense, however I want to use it on the iPad and the user is actually never saving the form. When they are done completeing the form, they just hit a "Submit" button that is from the iPad app to upload the form to a server, so there is no actual save process from the user.

Then add it to the Submit button's Mouse Up action...

The Submit button is not a button created in the form.

It is a button from the App itself.

Is there a way to have the time check/change everytime a field is filled or a button is clicked?

Would I have to put the code in each of the field to check time?

Yes, if you place the code under the custom calculation script of the text field.

You can use this:

event.value = util.printd ("HH:MM", new Date());
