Hello everyone. I'm currently having trouble with rtcwake.
My goal is to have my system wake at 01:00 am and then suspend at 07:00 am, everyday.
My cron for wake is:
Now, you may be wondering "why is your time set to 20:00?" Well, that's the first part of my mystery. The output of this command is:
So, as you can see, the output of rtc is 5 hours plus of the system time. I'm sure this to do with UTC and system time something or other, but it's beyond my understanding.
Part 2: I use webmin to manage my server. Before some one asks me why or to stop using it, please know that I just like it and I have no intention of not using it. That doesn't mean I'm not open to using terminal to set this particular wake/suspend schedule, but I'm currently trying to do it with Webmin.
Now that you know I use Webmin, I want you to know that I use it to schedule "pm-suspend" to run at the scheduled hour of "7". Now, I assume that schedule operates on system time, so maybe this means it will run at 12 noon. Setting it to run at "2" would probably be a patchwork solution.
So the question is two-fold:
Can I make system time/hardware time to match UTC?
Or, is there a smarter way to go about this?
I've done a million searches on this and it seems that there's tons of information available, but I don't have the knowledge to decipher it.
Thanks for any help.
