My Digital TVGOS is gone, but Analog TVGOS is still alive over cable. With that said, I won't be tearing into my unit until that goes as well and I loose the ability to set the time. The first things to try are Serial to USB adapter and possibly an Ethernet to USB adapter and attempt to to establish a communications link directly with the Linux operating system (Telnet, FTP, or shell login). It's a simple matter to set the time via linux commands.
