How to check if date/time was entered?

How can you verify that a date / time was entered in a field? We tried to convert the time into a long, and then check if null, but it doesn't like that.
starttime = time.getDStartTime().getTime();
if (starttime == null)
{
starttime = 0;
}
What do you need to convert the time to before checking (String?), or what can you use to check a long?

Use the DateFormat parse(String) method. It will throw an exception if the string is not a valid date.
 
I agree. Here's the link: http://aspose.com/file-tools
