Symmetricom's DomainTime II software has a DomainTime over HTTP option
using port 80 for just this problem. Accuracy is impaired compared to
the DomainTime protocol or NTP, but will easily satisfy your
requirements. You can get a 30 day trial version from the website at
http://www.ntp-systems.com/software_download.asp?ID=product_software_30day_trial.asp
and give it a go.

Hope this helps
