I have an IIS 7.0 server configured to rollover logs daily. However it appears that the logs rollover at 10am each day. How/where do I configure this so that they roll over at 1am?
The logs use UTC and roll-over UTC day bounaries, this is by-design.
You can switch to Local Time by checking the "[ ] Use local time for file naming and rollover" box on the Logging screen in IIS Manager.
Besides local vs UTC, you cannot specify a custom timezone or arbitrary point in time for the rollover.

I have a requirement where I want to run a test case in PDT time. So I tried to change date and time of my windows machine(a VM) but it gets automatically reverted back to current date and time . I want a help regarding that.
I have time server sync. checkbox off as well as windows time service and hypervisor time service is also off on the VM.
Please post your thoughts
I have a Linux server (CentOs to be specific) with npm installed. The server's timezone was UTC and I changed it to IRAN (+4:30).
Now my linux timezone is IRAN (say 7:00 PM) while my node Date() returns UTC (4:30 PM).
How can I change the default timezone of Node entirely (and not on a running applications)? I searched a lot and every answer I found was targetting node apps, not the node service in general. I want Node's timezone changed, not the app.
:( by the way, my CentOs does not have any GUI. Answers in text mode are welcome
I found the solution by trying different approaches.
First I changed the Timezone of Centos, and my application on pm2 was still on UTC timezone.
Then I changed the TZ var using cp /usr/share/zoneinfo/Asia/... and still no result.
Then I restarted my CentOs server excpecting the changes to take effect, but no result yet. After server was up, and pm2 reloaded my application, it was still using UTC timezone.
Finally I deleted my application from pm2, and then added it again. That was when my application started using the local timezone.
So keep in mind that no matter what you do to the "Linux TimeZone" or "TZ var", pm2 remembers the timezone of the moment you add your application, and keeps that somewhere and uses that as the timezone of your application.
I want to be able to change the date and time on my vm to dates in the past. Every time I change it, it automatically changes back because of this setting. Unfortunately I cannot change it because it is disabled. I am logged in as an admin on the vm. Any ideas?
Try this:
Hyper-V Time Synchronization Service, startup set to "Manual"
Windows Time Service, startup set to "Manual"
BUT based on this article, it 's not recommended so maybe the safest way is to add time offset in you program
I'm from Russia, and 1,5 days ago (at 2AM, Oct 26) our timezone (ok, offset of our timezone) has changed - from UTC+4 became UTC+3. Please, don't ask why now - it's out ******* goverment :( But it changed.
My home Win 8.1 machine updated automatically.
But only one (!) of my Azure resources is updated. One Cloud Service updated, while one more Cloud Service and 4 websites are not updated - they are still at UTC+4 offset.
I know, all Azure servers are in UTC in settings, but I speak about TimeZoneInfo data on them.
I'm requesting
var tz = TimeZoneInfo.FindSystemTimeZoneById("Russian Standard Time")
and this timezone is still
(UTC+04:00) Moscow, St. Petersburg, Volgograd
while my home machine is in
(UTC+03:00) Moscow, St. Petersburg, Volgograd (RTZ 2)
AFAIK, this depends on system updates on server - new timezone data must arrive prior to any time changes can actually happen. But why servers are not updated?
My one CloudService as working properly now, showing correct timezone info (can't show it), so at least one server is updated correctly, while others are not.
I made small website to test this: http://timezonetestrussia.azurewebsites.net/ (source: https://github.com/justdmitry/AzureTimeZoneTest )
It shows TimeZoneInfo.Local info and from "Russian Standard Time". At this moment, it shows this in Azure:
Id

(UTC+04:00) Moscow, St. Petersburg, Volgograd

While on my local machine it shows:

The most likely reason is that different services run on different Guest OS "versions". You likely have automatic Guest OS updates enabled (osVersion="*") which means that Azure is free to update the Guest OS. Different Guest OS versions withing the same family include different sets of updates. Things like rules for timezone adjustments are typically distributed using updates too.
Look at guest OS updates feed http://sxp.microsoft.com/feeds/3.0/msdntn/WindowsAzureOSUpdates - they cannot release a new OS to all users for months already. The process was started multiple times, they updates some of the users and then stopped the process. It's likely that your "proper working" service got the OS updated and the other services have not got the OS updated. You can perhaps verify this using Management API http://msdn.microsoft.com/en-us/library/azure/ee460804.aspx Get Deployment call.
I am researching if Azure can be updated with the new time zones, but I don't believe it is directly possible. Or rather, since you aren't given access to the OS that your Azure Web Site runs on, you wouldn't be able to apply the updates yourself. You will likely have to wait until the next major Azure Guest OS update. I will update this post if I learn otherwise.
If you can rework your program, you might instead consider using Noda Time. It has its own time zone data, which comes from the IANA time zone database. Be sure to use an updated .NZD file, as the Russian changes are covered in IANA 2014f or greater.
We are based in the UK and have a series of web services deployed to Azure. One of these automatically refreshes every 5 minutes and displays a 'Last refreshed at hh:mm:ss' message.
It appears that this is not taking into account daylight saving time as the time displayed is one hour behind local time. We suspect it is using UTC. We have tried setting
<globalization uiCulture="en" culture="en-GB"/>
in the web.config and programatically with no success.
Is there an easier solution to display the correct local time than having to determine the DST offset and applying it at every instance of 'DateTime.Now()?'
Thanks in advance for any help.
In the Azure Portal under Application Settings add a environmental variable with the name WEBSITE_TIME_ZONE with the value W. Europe Standard Time.
For other values, see: https://msdn.microsoft.com/en-us/library/ms912391(v=winembedded.11).aspx
#viperguynaz is correct, all of Azure runs on UTC. If you're running in Azure, then you should keep it running in UTC and not try to circumvent it as some things don't behave very nicely then. Instead, as a software developer, you should add the ability into your application to honor time zones and to handle data saved as and services running on UTC. Never use DateTime.Now but instead always use DateTime.UtcNow.
For more info on this, see this question.
Yes - Azure runs on UTC time. Read DateTime.ToLocalTime Method and TimeZoneInfo.ConvertTime Method for how to get the local time with time zone known.
We have a similar UK specific situation and we simply set the timezone using the timezone utility tzutil within a single line "elevated simple" startup task:
tzutil /s "GMT Standard Time"
We haven't seen any issues with this and the timestamps always match our expectations. This seems simpler than ensuring that every DateTime interaction in code is made local time / timezone aware.
I believe that this utility is only included in images of Windows Server 2008 R2 and beyond.
