interesting timezone requirement
« on: February 20, 2019, 08:17:27 AM »
Hi forum,

Having searched and search I seem to find all the answers for keeping your system time in sync with NTP (as that's what it does ;) )

BUT here's a random question - How can I keep in sync with a ntp server but then offset that time by a constant value such as say 1 minute ahead.

Yes, that's odd - but essentially I have a system that's powering a audio stream that has an almost constant 1 minute buffer.

So, I'm trying to find a way that I can accommodate this buffer time in the system time so that audio you hear is then closer to the real world time.

I know I could set time / date with "date" - but that involves losing the benefit of keeping the clock in some sort of "sync".

Not sure if this is possible in anyway? I looked at timezones but that obviously only helps with large jumps in time where as all I'd like to achieve is a system time 1 minute faster than ntp time it gets?

Not sure if there's any magical ntp.conf setting I've missed?

There was the thought to only use GetTime.sh and add a delay in time form when that script gets the value and then actually sets the value on the system?

But thought best I see if anyone has ever needed this type of strange time setup before :)

Many Thanks.

okay, so I'll answer my own question as seems you can set minute in TZ boot option. I've not tried yet but found this in more detail.

So will try and post my findings here.
