linux 系统时间同RTC时间有很大误差，而校时命令djtimex --compare不支持，得不到准确的误差值，不知怎么校时？？求助！！！adjtimex -h
adjtimex: invalid option -- 'h'
BusyBox v1.22.1 (2015-07-09 14:58:56 PDT) multi-call binary.
Usage: adjtimex [-q] [-o OFF] [-f FREQ] [-p TCONST] [-t TICK]
Read and optionally set system timebase parameters. See adjtimex(2)
-q Quiet
-o OFF Time offset, microseconds
-f FREQ Frequency adjust, integer kernel units (65536 is 1ppm)
(positive values make clock run faster)
-t TICK Microseconds per tick, usually 10000
-p TCONST
