I uploaded
test version 6 to
http://blockyskies.com which includes code to restore the system clock on exit for the hard drive installed version.
I used TOD code adapted from
this post (it had a minor bug in it) and it seems to work well for me in all of the emulated configurations I can test (including no RTC).
If anyone is game to test it on real hardware with a RTC, I would be very appreciative
