When trying to submit a change request in our ServiceNow instance, an invalid start date error is showing up.

[code]Solution: [/code]

The root cause of the issue is with the Client Script which has a invalid way of checking the format of the script.

For Example 

In this client script's code:

At line 18:
[code]

if (user.next()) {
		var start_date = g_form.getValue('start_date');
		var date_format = user.date_format;
		if (date_format == '')
			date_format = 'yyyy-MM-dd';
		var time_format = user.time_format.substr(0, 4);
		if (time_format == '')
==>			time_format = 'HH:mm:ss';
		var time_date_format = date_format + ' ' + time_format;
		var start_date_value = getDateFromFormat(start_date,time_date_format);

[/code]

The script is written to check the time as 'HH:mm', but the time is set as 'HH:mm:ss'. Due to this reason the error is showing up.

The validation of the date or time should be in the exact format as the way the system displays.
