How to retrieve time from the internet (bypassing PC clock)?
c++, time, trialware
Solution
Looks feasible and this is widely done.
Scraping of timeanddate.com can break if the site decides to change its HTML. Even a slight change in the HTML can break your scraper.
I would suggest you use a web service like earthtools. You'll have to pass the necessary arguments(latitude and longitude etc) in the URL and the response is XML which you can easily parse.
Problem
For my MFC/C++ unmanaged time-limited software needs, I'd like to get a GMT/UTC time-stamp from the internet (instead of relying on the PC clock time that can be easily changed). I already though about parsing the line "Current UTC"... line from http://www.timeanddate.com/worldclock/ (I think port 80 is more likely to be open than others) but I don't know how reliable this URL is... Please share with me your pros/cons or different ideas on this.
