Group,

For some reason my clock always shows the time to be one hour behind the actual current time. I am located in Central Time Zone and have the clock time zone set to -0600, but for example if my current time is say 1700 hrs, the clock will show 1600 hrs. And if i manually change the time to the correct time, either after i turn the radio off and leave it off for awhile, when i turn it back on later, the time is off by an hour again, it keeps getting 'reverted' back some how.

Anyone know what I might be missing or that needs to be adjusted or changed? I am thinking about taking another crack at messing around with the settings, but I am just about out of ideas...

Thank you,
Doug

The radio uses the time received from the GPS satellites as its time reference. It then applies the UTC Offset (Menu 927) to calculate the correct time for your location. So, if the GPS sats say the time is 11:52 UTC, you would need a UTC Offset of -6:00 to get a local time of 05:52 Central Standard Time.

The problem is that there is no DST setting in the Kenwood radios as some clocks have. Therefore, you have to manually change the UTC Offset twice a year to keep up with DST.

Since we are currently on DST in the U.S., the correct UTC Offset for those in the Central Time Zone would be -5:00. In the winter, when we come off of DST, the correct UTC Offset will be -06:00.

Slightly incorrect. GPS sats send time data in the form of GPS Week and cumulative seconds since the start of the current GPS week. GPS is week 1967(37.827 years) and GPS time is 480,130+\-seconds(5.571 days at time of post). Software then calculates and displays the time and date in a format folks are accustomed to.

GPS time started on January 6, 00:00h 1980. The attached photo is a Trimble TSC-3 Data collector and R6-3 GNSS receiver. There is a page that displays the GPS week and GPS seconds.
