I am getting ready to dive inside the S-3 and guessing that its got the original motherboard battery on the unit, so will replace it but want to get it back on time once its buttoned up.
Ideas or suggestions?
Motherboard battery failure will cause a time of day problem, but usually only if the unit is powered down; and the failure is catastrophic, the clock will be decades off, not minutes. When a computer is powered, the clock runs on wall current, not the battery. This true for almost all computers and I have seen no evidence anything different is true for TiVos in particular.
All computers drift to some extent; and there have been periods when the TiVo server clock was apparently offset a few tens of seconds for a period not too long ago.
In my experience, forcing a connection causes one's TiVo to synchronize with the TiVo server; I would try forcing a connection and checking the clock right away and then periodically for a day or two. If it syncs up during the connection and then gets steadily worse as time goes on, your TiVo has a drifting clock. If it is bad right afterwards and stays about the same, TiVo's servers are at fault. If it bounces all over the place there is either a hardware bug or a software bug, which bug will never be fixed, unfortunately.
