I want to display current time of the user's OS that is visiting the lander.
I was told it can be done with Java, but it's not the best option for phones as some don't support it.
Any tips/ideas?

Insert Date / Time in PHP
He meant the visitors local time not system time. PHP values display system time. You need javascript to get users local time.
