hwclock
|

-------
|
||||
|
||||
- (!!!) add "hwclock -c|--compare" to provide info about RTC frequency offset
|
||||
like "adjtimex -c", shell version:
|
||||
|
||||
#!/bin/bash
|
||||
date > /dev/null
|
||||
hwdate=$(hwclock -r)
|
||||
time1_sys=$(date +'%s.%N')
|
||||
time1_hw=$(date -d "${hwdate% -*}" +'%s')
|
||||
|
||||
while sleep 10; do
|
||||
hwdate=$(hwclock -r)
|
||||
time2_sys=$(date +'%s.%N')
|
||||
time2_hw=$(date -d "${hwdate% -*}" +'%s')
|
||||
awk "END { x = (($time1_hw - $time1_sys) - ($time2_hw - $time2_sys)) /
|
||||
($time2_hw - $time1_hw); printf \"sysclock/RTC frequency offset: %.0f ppm (%.0f
|
||||
ticks)\n\", x * 1e6, x * 1e4}" < /dev/null
|
||||
done
