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.
