I don't think that's correct. If your clock is off by 23 minutes you need to set the clock drift in Sleepyhead to 23 x 60 = 1380 seconds (same as RobySue in that SH thread). In the latest version 0.9.8-1 you can use hours, minutes & seconds. You can also set negative and positive values depending on whether the CPAP clock is running fast or slow.
To establish if your clock has drifted, turn the machine on at a very specific time (eg 10:00pm exactly) so you have a base time to calibrate to. (Or turn it off at a very specific time, works just as well).
