I've seen a few systems mixing up their clocks, sometimes using the database server clock, sometimes the web server clock, sometimes the user's local clock. Whatever clock you're using, be consistent about it. Users can and do configure different time zones than where they're actually located, e.g. if someone in India is working with a team in the UK, they'll probably have Indian time on their local clock, but select UK in their user profile. Also, some people travel.
