What's the best way to periodically get time and date if your customers are big businesses with hostile IT departments?
A great solution I've used plenty of times is to query websites like google.com. I use it whenever my rtc on my Linux laptop gets reset (as long as it's still in my history. Otherwise I just set it manually).
