The question is what causes the drift and is it really predictable... but you can observe and if the target environmental conditions are stable, it may work. If you can 'afford' to spend the money on a ESP8266 WiFi module, you go once in a while to the Web and get the time for free from there. Power seems not an issue, I guess, because running a multi 7-Segment LED display needs to be fed as well.
