N2024 Time Synchronization Update

My switch is firmware updated to 6.7.1.22.

  

The switch was operating standalone when I did this.

I updated the SNTP Server, Time Zone and Summer Time Config generating the following lines in my running-config file:  (and they look fine to me)

sntp server 192.168.1.254
clock summer-time recurring USA zone "EDT"
clock timezone -5 minutes 0 zone "EST"

I bring up the System > Time Synchronization > Clock Window and I see the following:

I realize the image may be hard to read but under the yellow it says UTC - 5.0 (what I expect) under the orange it says (UTC - 4.0) (not what I expect which is (UTC - 5.0) since the date is in February) but the time appears to be correct.

I then strongly advise against clicking the apply button.  Under the orange that used to say (UTC - 4.0) it now says (UTC + 6.0).  Under the yellow where it used to say UTC - 5.0 it now says UTC + 5.0.  The time has shifted about 10 hours too.

My running-config file after that change now contains:

sntp server 192.168.1.254
clock summer-time recurring USA zone "EDT"
clock timezone 5 minutes 0 zone "EST"

Am I doing something wrong or is this maybe your issue?

Thanks
