Set Time Automatically In Different Time Zone

I have a laptop with Windows 10.0.18362 (64-bit) installed.

As I frequently travel to a different time zone, I went into Settings
- Date & time, and made sure that the Set Time Automatically and Set
Time Zone Automatically are both turned on.

And yet, when I am in the other time zone, my laptop still shows the
original time as if I had never moved to the other time zone.

Yes, I know that I can manually change the time in Date & time, but...
is there a way in Windows 10 to _automatically_ adopt the time of the
time zone I am in?

Hey NymShifter,

No you don't know. That's not the way to change the timezone.

but...

time zone I am in?

Yes. The automatic way is to change the TimeZone NOT date & time as you
have been doing. These are two different things and sooner you know the
difference the better it will be for man-kind.

There is a slider to turn on the automation.

Great.

But you know they didn't make it that easy.

Your machine has "location awareness" sliders.

Such things work best on mobile devices.

You can manually enable such things on a desktop,
but in essence, it "gives away" where you are.

That would be the tradeoff.

This article hints at the requirement...

https://support.microsoft.com/en-us/...ce-and-privacy

"How the location settings work

The device location setting enables certain
Windows features such as auto-setting the time zone
or Find my device to function properly."

Microsoft could deduce where you are, if things
like Wifi Sense were still around. (That used to
record SSIDs, and MSFT could build a map using
data collected from all the OS users.) The method
of doing reverse-lookup to get your ISP head office,
can be off by several time zones (as a method).

Mobile devices with GPS, allow readily determining
location.

Visual Studio had some means to test this, perhaps
back in 2015 or so.

Have you consider adding the second clock for the area into which you
are traveling?

Right click on Clock (right end of the toolbar), Adjust date/time,
Related settings, add additional clocks.

Judge your ancestors by how well they met their standards not yours.
They did not know your standards, so could not try to meet them.

Are you hibernating your laptop when you close it or shutting it down.
See what happens when you shutdown and later boot. Could be the
timezone doesn't change until the next time Windows does a clock sync.
On boot Windows does the clock sync; else, you have to wait until the
next scheduled poll for a clock sync (other than going into the Control
Panel - Clock and Region - Date and Time - Internet Time tab, Change
Settings - Update Now. Instead of all that dialog navigation, you can
force a time sync at the command line in an elevated command shell (like
in a .bat batch file):

net.exe start w32time
w32tm.exe /resync

Some users will use 3rd party time sync programs where they can more
easily configure how often to sync rather than use registry settings,
and force an immediate synchonize. Or you could define an event in Task
Scheduler to run at the interval you want; however, since these are
console commands that need to run in an elevated command shell, you'll
see a flicker on the screen as the console window opens, runs the
commands, and then closes. In that case (where you aren't around to
wait for the w32tm command to finish, add the /nowait switch; run "w32tm
/?" to get help). Instead of use the net command to ensure the time
service is running (when you do a sync), you could use SC (Service
Control Manager) program:

sc.exe start w32time

If you go the Task Scheduler method (which you can run on demand or run
the batch file in an elevated command shell), make sure to go to the
Conditions tab and enable the "Start only if the follwoing network
connection is available". No point in trying to connect to an NTP
server if your host doesn't currently have a network connection.

There are registry entries where you can change the time sync settings,
like which NTP server to use, add to the list of NTP servers, the
polling interval, etc. However, unless you choose a severely short
polling interval, you will be waiting until the next poll interval
before there is a time sync. There is no time sync (or anything else)
happening when the computer is powered off, like in hibernation mode. I
don't know if time sync is operative in sleep mode.

You'd think GPS would let the computer automatically set the timezone.
The boundaries of the timezones are well know, so a database of those
regions could be looked up via GPS coordinates. Yet I've read the
Android OS won't set the timezone automatically based on GPS, so maybe
Windows doesn't, either.

Does your laptop have a cellular radio, so it can use cellular service
(voice and data)? The cell towers transmit the time, and that's what
the smartphones use to adjust the timezone.

I recall there was a problem with timestamps under FAT[16/32] where it
got screwed up or was interpreted wrongly. NTFS took care of that, so
the timestamp is relative to UTC, so it didn't matter which timezone the
OS was set to.

Are you using wi-fi hotspots with your laptop? Hotspots can be (but not
mandated to be) configured to transmit their time and timezone as part
of their location specific attributes.

The service responsible for the automatic timezone adjust is
tzautoupdate; however, nothing popped as a likely candidate in the
Services app (services.msc) or from "sc query". I found it in the
registry at:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Servic es\tzautoupdate

Apparently the OS gets the service name from the indexed resource (200)
inside of @%SystemRoot%\system32\tzautoupdate.dll. Oh, joy. I then
right-clicked on the .dll file and looked at its Details tab where the
File description field was "Auto Time Zone Updater". Now I found it in
services.msc. For my on my desktop PC that obviously doesn't move
around, I have disabled the "Set time zone automatically". As a
consequence, the Auto Time Zone Updater service is shown as Disabled for
its startup state. When I enable this option and refresh the Services
app, this service changes to Running state with Manual startup mode.
Manual startup mode means something has to call the service to run it.
However, some services only run for awhile when requested to start or
after being called by some other process. I did not hang around for
half an hour to see if the service state eventually changed to Stopped.
After you enable this option, go into the Service app to make sure the
Auto Time Zone Updater service is running or, at least, set to Manual.
I would think this service would not keep updating the timezone, but
instead check when there was a time sync.

Double-click the service to open its properties window. If Running,
click the Stop button. Once stopped, click the Start button. I'd
repeat this a few time to make sure the service is responsive to start
and stop requests. If the service won't start, there is a problem with
the service.


_Hazard of changing the timezone with FAT_

http://ask-leo.com/why_do_file_times...me_change.html
"In the FAT file system, when a file's timestamp is written it uses your
local time."
"In the NTFS, all timestamps are written in Coordinated Universal Time
or UTC ..."

With FAT, it was recommended not to change the timezone as you
travelled. With NTFS, not a problem. You didn't mention if your laptop
drives are formatted using FAT or NTFS. While this is a Windows 10
newsgroup and most users would be using NTFS, Windows 10 can be used
with FAT32, especially if the user has been upgrading from Windows
version to Windows version instead of doing fresh installs.
