Setting Clock Time locally

[Bloork]

I have been using my Tivo without needing the EPG information. It works fine for me so long as the clock is reset every month or so, by way of a call to altepg.
I was wondering if there is a relatively easy way to get the clock reset by directing the daily phone call to my computer. so my queries are:

1. Can I access the serial I/O stream prior to the modem? In a previous life I programmed two way serial port scripts in order to analyse dumb terminal dialogue with remote computers, and emulate them using early microcomputers.
2. Can anyone assist with say Python programming in order to have a dialogue with the Tivo making its daily call, so as to skip through and only set the clock time? I am aware of the need for handshake and modem control etc, but after my engineering days of the late 1970s have had very little programming experience.

I still think that the Tivo is a great machine - still better at most things than any of the competition.

You should have a program called settime on your Tivo which may help you
Usage: settime [YYYYMMDDhhmm[ss]] [-rtc]

Or you have ntpdate which will connect the Tivo to a ntp time server

Very helpful pointer. It set me off searching the web for full technical details of how to do this from scratch (with my very limited recent experience).
For anyone else looking to set the clock locally from their computer I found the following three steps extremely clear:

Very many thanks and best wishes for 2016
