Daylight Saving Time

Last spring, we discovered that a small number of our customers experienced an issue with the start of Daylight Saving Time taking effect a week early in their Venus 1500 V4 software.

Since becoming aware of the issue, we have taken measures to resolve it by rewriting the firmware for our display controllers. Most people who experienced this issue have had their firmware updated and will not have to worry it anymore.

When we first found out about the issue last spring, we put in place a temporary solution to help out those who were calling in for help before we were able to rewrite and update the firmware.  Because of this, there is a small chance that those people could see similar issues with the end of Daylight Saving Time.

Questions and Answers

Q:  Who will this affect?

A:  A small number of people who may have used our workaround from last spring, or have not updated their firmware to version 3.11.4 for M3 controlled displays or version 3.16.2 for M2 controlled displays.

Q:  How will I know if I am affected?

A:  There are 2 ways to know if you are affected.  If your clocks do not automatically fall back 1 hour on Sunday, November 6 at 2:00 AM then there is a possibility that you are affected.  If your clock falls back 1 hour before the scheduled fallback time on November 6th, then you are definitely affected.

So, if your display time falls back 1 hour on November 6 at 2:00 AM then you are not affected and you don’t have to do anything. If your display time falls back before November 6th, or does not fall back at all, then you could be affected.

Q:  How can I check to see if I am affected?

A:  Under Display Status on the left side of your Home tab it says Daylight Savings Time and it will either say Enabled: Active, Enabled: Inactive, or Disabled: Inactive.  If it says Enabled: Active, then you are currently in Daylight Saving Time.  If it says Enabled: Inactive, then you are currently in Standard Time.  If it says Disabled: Inactive, then you are not utilizing the Daylight Saving Time feature in your software.

So after November 6th, it should say Enabled: Inactive for those of you using the Daylight Saving Time feature, or Disabled: Inactive for those of you in Hawaii, Puerto Rico, most of Arizona, and some parts of Indiana who aren’t using the Daylight Saving Time feature.

If you have a time message running on your display, then you can also look at the actual display itself to see if it is showing the correct time or if it is an hour off.


If you suspect that you are one of the few people being affected by this issue, then please refer to our knowledge base article entitled, “Galaxy display with DST is off by an hour, firmware is out of date” for step-by-step instructions on how to resolve the issue.
