I hope I get an answer on this question. I get leavening the DST off and will leave it off. Do I leave the time setting itself the same also or go forward one hour like the clocks. ? HEM27EC mount.
Daylight Saving Time reminder.
How does one go about turning off DST in the mount? I am using the AM5 mount with ASIAIR Plus (both using latest versions of software and firmware). When I open the AM5 app I do not see any setting to turn DST off!!
How do you turn off DST on the AM5? The ASIAIR app tells you to turn it off, but gives you no clues how to do it. I went into the mount app and there is no way to change the time?
How do I go about doing this?

Chen doesn't know, he doesn't use the AM5 mount. I have the same question. The newest version of ASIAIR (2.1) has this on the mount settings page:
"Please ensure that DST is disabled on HC, It's normal that the time on the mount is 1 hour earlier than your local time."
Yet I don't see any way to do this using the mount's app or the mount's hand controller (HC). Does anyone know what this is about and how to ensure that the ASIAIR Plus and the mount are communicating successfully in regard to guiding, tracking and the meridian flip?
Thanks!

How do you turn off DST on the AM5?
Hand controller?
Confused!
Please help us on this. I don't see instructions on how to do that anywhere.

Aleastro How do you turn off DST on the AM5?
Hand controller?
Remember that DST is just an artifact placed on the UTC Offset when Summer arrives. UTC itself does not change, and your longtitude does not change.
Can you set UTC time, and Longitude through your Hand Controller? If so, do that. And if it needs Local Time, set the local time to Winter Time (Spring forward, Fall back).
That should be completely equivalent to turning DST off.

I have the ZWO AM5 and the ASIAIR PLUS.
I think it's correct now. The app shows 1 hour earlier than the time in my computer or phone right?
Thank you!

I think that's true, it appears ZWO has taken into account DST, my app is showing the same thing, DST started Sunday in California and my mount's time is exactly 1 hour earlier than the actual time.
I am guessing that when ZWO added in the mount's settings "Please ensure that DST is disabled on HC. It's normal that the time on the mount is 1 hour earlier than your local time" it's for other manufacturer's mounts, not the AM5. But I am not really certain. All I know is that I haven't been able to find any way using the AM5's HC to change DST settings, nor can I find such settings in the AM5 or ASIAIR Plus apps.
Let's hope this is resolved;, I see of no other way to ensure that the LST is the same on the app, the mount and the ASIAIR Plus device. Just one more reason why I think DST is one of the stupidest ideas ever invented. States and nations that don't use it are making life easier for its citizens, well, at least in that one respect.

I went out Wed. night (first time since switching to DST), and was not able to polar align, and am guessing it was due to DST/AM5/ASIAir issue. Yesterday, I set up at home, and verified that the AM5 and the ASIAir time were the same. I "synced", and it changed the AM5 time to one hour earlier. At home my iPad knows its location, but at a remote location it does not (lacks gps, and relies on wifi to fix its location). Because of that I have to edit the location when first opening the app on the iPad. I am then reluctant to "sync", since their iPad location is not correct. Now, I'm wondering if I cannot use the iPad when I'm remote. Does anyone have an opinion, or information as to this situation? Or do I not understand this issue. If so, please explain.
Thanks,
John
It is odd being that the AM5 Hand Controller has no DTS Setting that I could find. 
For those of us who were not aware of this issue, like myself. I guess you have to stay glued to these forums to catch something like this. I hope there is a better resolution for this. I can't believe in 2023 we have GPS/time issues and going back to the beginning of this thread, to 2021??? I set up tonight and got NOWHERE due to this issue as the last time I set up was before the time change and everything worked. I'll try to set it up again and go through all the settings, but hey ZWO, do we really need to wait or put our mounts on hold until DST starts up again?

This is particularly true since one company controls:
- ASI AIr
- ASI AM5
- ASI Air App
- ASI Mount App
- All firmware
There is really no excuse for this integrated system to fail.
johnrsims43 , I would agree, but ZWO is quite responsive on updates for all their products.
11 days later
I connected HC To Mount and connected to HC's WIFI and invoked ASI Mount App: App reads DST settings correctly. There is no setting to turn off DST in ASI Mount App as well.
But with ASI AIR App, it reads UTC-5 ( I am on east coast). I am not sure why two different apps for Same Ecosystem (ZWO Products) / Vendor should read differently. It almost seems like a problem with ASI AIR SW issue.
Here in the Netherlands it's summer time now, and my Asiair plus had an DST issue with my Skywatcher EQ6-R pro. I turned off the DST but still I this error in my asiair app.
What can I do?
My local time was 20h34m. But Asiair it shows in the mount options 18h34?
I don't get it anymore, do I need factory reset in with the handcontroller of my EQ6-R PRO?
Aleastro I have to change my time in my tablet? So my EQ6-R PRO is not a few hour away from the DSO? I live in the Netherlands and the summertime is started, my UTC is +2. Do I have to go 1hour earlier in my tablet? Because in the wintertime I didn't have any issue.

stefanastro Because in the wintertime I didn't have any issue.
In Winter, you were running "Standard Time." The only time ASIAIR understands.
The ASIAIR has a problem undertanding time because it derives time from "Local Time" instead of directly using UTC that is obtained from iOS and Android APIs. If it had used UTC instead of local time, none of these problems with Meridian flips would occur.
What you can try to do is to use your Mount's handcontroller and check if
1) UTC is correct, and Longitude is correct. If they are correct, you are done since most mounts use UTC and Longitude to determine Local Sidereal Time.
If not,
2) see if you can set the UTC (some mounts have GPS, and you can simply depend on that). Ditto Longitude, and mounts with GPS can set that for you too.
if the mount's UTC is wrong, try
3) set the Local Time to the true Local Time minus one (i.e., set the time as if it is still Winter), AND set the UTC offset in the mount so that it corresponds to the UTC offset under Standard (Winter) time (it will also be 1 hour different from UTC offset under Daylight Saving Time).
After connecting with ASIAIR, check to make sure the ASIAIR app does not modify these two numbers behind your back.
As a sanity check, place your mount so that the OTA points to a location about an hour east of the Meridian (you can use an inclinometer against the OTA tube -- each hour corresponds to 15 degrees of incline, if your mount does not have setting circles on the RA axis). There are digital inclinometers at Amazon for less than $20 that are more than accurate enough for this kind of measurements. I have this dual axis inclinometer since it saves time when leveling a tripod, but you can just go find a $15 inclinometer if you just need to know the incline of the OTA tube.
https://www.amazon.com/Digital-Protractor-DXL360S-Inclinometer-0-01°resolution/dp/B077T7XW7X
Then go into ASIAIR AutoRun and set up a fake autorun and see what it reports as the time before the next Meridian flip. If your OTA is tilted 15 degrees east of the Meridian, and the AutoRun says you are 60 minutes (time) from a Meridian flip, then the times in the ASIAIR and the mount are in sync. (i.e., 15 degrees per 1 hours of time to Meridian).

Step 1 i did, but still 1 hour earlier while i set in the Skywatcher EQ6R pro handcontroller UTC on +01.00 and my Longitude correctly on my location East.
Step 2 my mount dont have a GPS.
Step 3: i did that step too but no succes, my local time minus 1 and the UTC 01.00 my standard winter time or the CET in europe.
So what can we do now?

stefanastro So what can we do now?
You mean that after you have set all times to Winter (Standard) Time, that AutoRun is still giving the wrong time to flip?
but no succes
No success in what? Did it not accept the winter UTC Offset, or did it not accept the Local winter Time? Or is a 15 degree east of meridian not show up as 60 minutes before Meridian flip?
Be sure not to sync the ASIAIR to the mount. It might be setting things to the wrong times again. The ASIAIR is full of bugs. If you expect the rest of us to help you, you need to explain everything that you see verbatim, instead of assuming we can see what you are seeing. Most of us don't even have the same mount that you use.
Chen
I think make a mistake. LST is not the local time in my country.
I found what the correct LST in the Netherlands is.
I'll let you if my mount is back to normal.
