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.
Thanks.
