Windows/Linuxとデュアルブートで時計が９時間ずれるのを直すコマンド

$sudo hwclock -v -w -l

hwclock from util-linux 2.38.1
System Time: 1726293071.864511
開こうとしています: /dev/rtc0
Using the rtc interface to the clock.
Last drift adjustment done at 1726293055 seconds after 1969
Last calibration done at 1726293055 seconds after 1969
ハードウェアの時刻は UTC です
ハードウェアの時刻が ローカル時刻 に設定されているものと仮定します。
RTC タイプ: 'rtc_cmos'
Using delay: 0.500000 seconds
missed it - 1726293071.866771 is too far past 1726293071.500000 (0.366771 > 0.001000)
1726293072.500000 is close enough to 1726293072.500000 (0.000000 < 0.002000)
Set RTC to 1726293072 (1726293071 + 1; refsystime = 1726293071.000000)
Setting Hardware Clock to 14:51:12 = 1726293072 seconds since 1969
ioctl(RTC_SET_TIME) に成功しました。
Not adjusting drift factor because the --update-drift option was not used.

System clock synchronized: yes
NTP service: active
RTC in local TZ: yes

Warning: The system is configured to read the RTC time in the local time zone.
This mode cannot be fully supported. It will create various problems
with time zone changes and daylight saving time adjustments. The RTC
time is never updated, it relies on external facilities to maintain it.
If at all possible, use RTC in UTC by calling
'timedatectl set-local-rtc 0'.
