<p class="MsoNormal">Hi all,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><span lang="EN-US">It seems I’m bothered by an old issue again, though googling tells me, I am not the only person effected….<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The general issue arrises when dual-booting:<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Ubuntu_18.04 uses UTC, derived from NTP<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Windows uses Local Time, derived from hwclock.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Normally the two can co-exists together, except, when stopping Ubuntu, System-D writes its time back to the hwclock.
<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">No big deal for Ubuntu (as it will use ntp), but a source of irritation under Windows.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I do know several suggestions, like:<o:p></o:p></span></p>

</span></span></span><![endif]><span lang="EN-US">Make Windows10 use UTC instead of local time.<br>
This would solve everything once and for all FOR ME, but not achievable for others.<br>
<br>
<o:p></o:p></span></p>
<p class="MsoListParagraph" style="text-indent:-18.0pt;mso-list:l0 level1 lfo1"><![if !supportLists]><span lang="EN-US"><span style="mso-list:Ignore">b)<span style="font:7.0pt "Times New Roman"">
</span></span></span><![endif]><span lang="EN-US">Make Ubuntu_18.04 use local time, with: “timedatectl set-local-rtc 1 --adjust-system-clock”<br>
However, I’m about to switch to Kerberos for several services, so I must use a reliable source for time.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">It seems that system-d is the culprit, in initiating the writing of the current time back to the bios/hwclock.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Is there anything I can do, to stop system-d causing this inconvenience ?<o:p></o:p></span></p>
