Take a look at http://www.vanheusden.com/time/omnisync/

OmniSync is a driver for NTPd for people who are firewall-challenged. It
enables systems to sync time when port 123 (UDP) is blocked. It allows
you to sync against the daytime service (port 13 tcp/udp), time (port 37
tcp/udp), SNTS, ICMP, SNMP, precision time protocol (PTP - IEEE 1588),
(S)NTP via a socks5 proxy server, http and https (both also via proxy
server). It doesn't directly set the clock but uses NTPd for this as
this enables you to have multiple time sources as well as bad-chimer
detection etc.
