How to Adjust Jantek Time Clocks for Daylight Saving Time?

In accordance with the Energy Policy Act of 2005, Daylight Saving Time will now begin on the second Sunday in March and end on the first Sunday in November.

To ensure that your clock is updated to accommodate this change, please check the following:


Obtain a status report from the clock by going to:
  -> Clock
  -> Time Clock Configuration (JTA-350)
  -> Time Clock Status Report.

Alternatively, from the clock itself, press CMD, CMD, then password 1,2,3,4,5,6, ENTER. Press 1 for Version ID and check the date listed on the right side of the first line.

The letter on the firmware represents the year and the numbers represent the month and day i.e. G0203 represents February 23, 2006. JTA350 clocks with a firmware revision of G0203 or later are updated for 2007. 256K clocks require G0706 or later.

If your clock does not have a firmware of G0203 (G0706 for 256K clocks) or later, please contact your local Jantek dealer or contact Jantek directly for a clock upgrade. If needed, Jantek will provide loaner clocks during the upgrade process for a fee.


On your login screen, check the release date of your Jantek installation.

Hand readers can be updated from within the Jantek software. Go to:
  -> Clock
  -> Time Clock Configuration (Hand Reader)
  -> Configure RSI Reader.

Select your site, then click on “Read From Clock”. Go to the 4th tab “Daylight”.

If the revision date of your Jantek software is Feb 10, 2006, or later, simply click “Compute”, then click “Write to Clock”.

NOTE:If your software is older than Feb 10, 2006, you will need to manually enter the dates before writing the data back to your clock.


The Phone Punch software utilizes the Java Virtual Machine, which should be updated. You can download the JDK US DST Timezone Update Tool found here
