0S Non-Proxy Atomic Sync allows you to perform time synchronizations, even if NTP (Network Time Protocol) is blocked by a proxy or a firewall. The software extracts the time from regular HTTP web pages, rather than using the NTP protocol, thereby bypassing the firewall - as long as you have access to the Internet. We found the synchronized time to be slightly inaccurate (within 4 seconds), however unless you depend on on-the-second time synchronization, the software provides a good alternative, and is surely better than no synchronization at all.
