John, Maybe helpful for you, maybe not. But you could look into the wheezy package fake-hwclock, which keeps time as close as possible to accurate time between reboots. Which would then make that one minute delay at least bearable. The problem I'm thinking you're running into here is that it takes a while for the OS to come up. So until the system is read to take care of reading the real time clock . . . Perhaps you could find, or write a kernel module that loads time from the rtc at early boot ? But non of this is anything I'v personally had hands on with, except fake-hwclock. On Thu, May 19, 2016 at 10:33 AM, John Baker <[email protected]> wrote: > My apologies to All: I'm an interloper.
