are also other ways to set the active time zone across computers. For example, if they are in a domain you can use group policy to update registry settings.

processes typically take. In other words, it is simply an out-of-band, purpose-built update process. Such a process would be helpful when governments do not allow enough lead time for updates to get created and distributed, such as described in my blog post: </span><a href="https://codeofmatt.com/on-the-timing-of-time-zone-changes/" style="font-family: Calibri, Helvetica, sans-serif; font-size: 12pt;">https://codeofmatt.com/on-the-timing-of-time-zone-changes</a><br>

My two cents of an admin of hosts (mainly Windows) that travel back and forth <br>
thru the seven seas (namely Cruise ships).<br>
<br>
Short version: TZ sync is a pain in the arse.<br>
<br>
Long version.<br>
You cannot use UTC for all the hosts because, for instance, some of them show <br>
information to the guests or are used to manage crew shifts (always expressed in <br>
ship time).<br>
<br>
On some ships the so called "master clock" has two NTP servers: one "classic" <br>
UTC and the other with ship time.<br>
<br>
We cannot use ship time NTP server because NTP clients (correctly) assume that <br>
NTP is about UTC, while the local time is just a "logical view" of NTP. If we <br>
sync Windows hosts with ship time the result is a mess (somebody said "Kerberos"?).<br>
<br>
We concocted a simple way to sync TZ between Windows hosts.<br>
<br>
The "TZ Server" runs the command<br>
<br>
tzutil /g > c:\tz\tz.txt<br>
<br>
C:\tz is shared as TZ<br>
<br>
Every client issue the commands<br>
<br>
set /p TZ=<<a href="file://"></a>\\TZSERVER\TZ\TZ.TXT<br>
tzutil /s "%TZ%"<br>
<br>
<br>
The procedure is tested on Win2016, 2012R2 and Win10<br>
