I have the same issue here.

It looks like all my devices (HS100 and HS110) that are running fwVer=1.2.6 and deviceHwVer=1.0 do not get the correct time.

 

I did an update of all devices, using the KASA app.

I did a time-sync using the KASA app.

 

Still the devices running fwVer=1.2.6 have a time offset of one hour!

 

My othere devices (with fwVer=1.5.6 and deviceHwVer=2.0) are getting the correct time.

 

This clearly looks like a bug in (fwVer=1.2.6, deviceHwVer=1.0) - can someone @ TPLink have a look at this?

Same issue for me I have six HS100's 4 running FW/Ver 1.5.10 work correctly and sync time However the 2 running FW/Ver 1.2.6 are one hour in advance.

For your information:

 

I filed a support-case with TP-Link about this.

@Nabiki 

I have the same issues and have both f/w version of HS100 plugs. I usually have it set to europe/London and it has been ok but now its shows the device time 1 hour ahead. It does the same for GB but the time is corrected when either Gb-Eire or GMT is selected however as I use sunrise and sunset feature it is still stating the sunset in an hour ahead of the acutal sunset even when both the device and location time is correct. I am at home so the sync is the same as the devices.

 

this appears to be a bug as the plugs now have the correct times and the location sync has been done with both the location/Device time correct for me its the sunrise and sunset that hasn't reflected the changes in BST to GMT. 

 

This is basic stuff TP Link 

Same for me. It was a rude awakening this morning when the light came on at 5 instead of 6am... Thanks a bunch! 

 

15 out of 18 plugs for me are wrong. 

 

All v1 hardware are wrong. 

 

V2.1 & v4 hardware are OK.

@kasa007 

Good day,

Thanks a lot for your kind feedback.

Sorry for the delay.

We had some feedbacks since yesterday due to the DST change and our senior engineers are working on it.

Please wait for a while for further updated news.

Thank you very much for your understanding and support.

Information des TP Link Support Germany: Momentan kann unser Cloud-Server nicht den richtigen Zeitpunkt senden, wenn das Gerät auf Berlin eingestellt ist. Dieses Problem wird sehr bald mit einem Update behoben . Als vorübergehende Lösung können Sie die Zeitzone manuell in Afrika-Algerien ändern. Dies ist auch ein UTC +1. Vielen Dank und wir entschuldigen uns für die Unannehmlichkeiten

As a temporary solution you can manually change the time zone in Africa-Algeria. This is also a UTC +1, thank you very much and we apologize for the inconvenience

@Tutti_Bomovski 

Even if you change places, there is a difference between V1 and V2.

There is a difference of 3 min. Why is it like that ?

In addition, you should be able to choose eg 30min +/- before or after sunset / sunrise.
