Restrict user selecting past date and time in catalog.

[WaseemM]

I have a code block with restricts the user to select past dates, but I'm not able to restrict the past time. For example, my current date and time is 2025-12-11 01:30:00.  I want the user to be restricted to pick the time of 2025-12-11 01:25:00, which is the same day but a past time.

function onChange(control, oldValue, newValue, isLoading, isTemplate) {
    if (isLoading || newValue === '')
        return;

    var value = g_form.getValue('snapshot_creation_time');
    if (!value)
        return;

    // Convert the snapshot_creation_time to a time object
    var snapshotTime = new Date(value);
    var currentTime = new Date();

    // check if snapshot creation time must be in future
    if (snapshotTime <= currentTime) {
        g_form.showFieldMsg('snapshot_creation_time', 'Snapshot creation time must be in the future.', 'error');
        g_form.setValue('snapshot_creation_time', '');
    }
}

Hi @WaseemM 

There is no need to write this error—you can use the Catalog UI Policy and restrict the past-date selection.

and in script section add error message

I didn't know that we could do this with UI Policy.

I just made it as shown below according to my requirements. Thanks!

You used UI policy only mate.

I assume your variable is a Date/Time type? If so, you could try using getDateFromFormat as described here. Example based on your use-case below:

function onChange(control, oldValue, newValue, isLoading) {
    if (isLoading || newValue == '') {
        return;
    }
	var nowDateTime = new Date().getTime();
	var selectedDateTime = getDateFromFormat(newValue, g_user_date_time_format);
	var isFutureDateTime = (nowDateTime < selectedDateTime);
	alert('isFutureDateTime: ' + isFutureDateTime);
}
