Just to add to the Chaos... I was paying around with the time and date as I am in a different time zone than what was already set on my VNAh4. The only place that I can see it's clock is under the CONFIG>VERSION location. As someone else mentioned its use in file management (photos/files) but that's about the only location I actually see the time. Not sure that answers your question any but I hope it helps some.
