Hey Andy.

I just saw a patch with a printk for rtc time from Mark Salyzyn.
https://lkml.org/lkml/2017/7/18/885

Any idea if you want to push this extension?

I like the concept and still think it could be extended a bit more.

from: https://lkml.org/lkml/2017/6/8/1134

My preference would be for %pt[type]<output style>
where <type> is mandatory and could be:

        r for struct rtc_time
        6 for time64_t
        k for ktime_t
        T for struct timespec64
        etc

and <output style> has an unspecified default of
YYYY-MM-DD:hh:mm:ss

Perhaps use the "date" formats without the leading
% uses for <output style> for additional styles.
