DISCLAIMER: I hope that my poor english let me understand well your words.
Yes, I'm using S3 with /proc/acpi/alarm without issue; the same for
wakeonlan, then I'm able to resume the mythbox either with scheduled
timings (acpi alarm) or on demand with magic packet.

First question: what does it mean "stella" ??

ok. I thought that the time format used from mythwelcome was hardcoded
and designed for nvram (which afaik use a pretty odd system).
is that true?
from what you write, it seems that is suitable also for /proc/acpi/alarm.
or, do you means that I've to modify your string in something like
"echo yyyy-dd-mm hh:mm > /proc/acpi/alarm" ? mmmh, I'm not

I think crappy BIOS, according with the mythwiki page.

ok. but I've yet to understand the "mythsettime" part.

thank you
