UTC vs Local Time - Dashboard

Hi again,

I am using Dashboard 1.1 plug-in for OpenCPN. It is working well, but one thing I can't seem to change is the display of time. It comes up with UTC in both Clock and Sunrise/Sunset. I would like this to display Local time. Is there an option I am missing here?

Thanks...Steve

Re: UTC vs Local Time - Dashboard

Hello all,

Would anyone be able to answer this question? Is everyone using UTC on their Dashboard, or can it be configured to show Local Time?

Thanks!

Re: UTC vs Local Time - Dashboard

Hoi Steve,
The clock is taking it's data from gps nmea stream. So unless you can program your gps to send local time, it will show gps time. gps time is almost the same as UTC (different about 16 or 17 seconds)
Dirk
PS
for local time you have a clock in your OS taskbar.

Re: UTC vs Local Time - Dashboard

That answers that...I was thinking it was coming from the PC time. In checking the docs for my Furuno GP-31, the NMEA output data stream is exactly that, UTC. I have the offset time set in the GPS, so my GPS screen shows local. But the NMEA data doesn't use that, it is quite clear. RMC for example sends "UTC", not "UTC offset based on your setting".

Hmmmm...possible new feature in OpenCPN down the road, or do I have to replace my GPS?

Thanks for the info.

- Steve

Re: UTC vs Local Time - Dashboard

Not to beat this to death, but I am curious. I was thinking about this the other day. NMEA is standard strings, so regardless of whether the GPS is new or old, NMEA 0183 sends the same string data.

So does that mean that everyone using OpenCPN is seeing UTC? If there is no option to use PC time and NMEA doesn't have a string that utilizes UTC plus the offset programmed by the user into the unit itself, then that means everyone is seeing UTC on OpenCPN.

Is my logic goofy?

Thanks...

WS...
NMEA sentences contain UTC time. Dashboard plugin in OpenCPN shows UTC time taken from those sentences and independent from your computer's clock (most of the time) for all of it's users.
Local time is in the lower right corner of your screen for almost all the computer users out there, so I felt like I can afford to be a bit lazy and implement those 2 instruments UTC only. If someone does not like, patches are welcome.

Re: UTC vs Local Time - Dashboard

For nav instruments on your PC, I would take a look at Polar Com from Polar Navy, if you are on Windows as I don't think they have support for Linux or Mac.

Has much more flexibly then the Dashboard plugin (not bashing what is available within OpenCPN, as the basics are there and open for anyone to expand on). Can show local or UTC, can show Mag or True heading/COG, etc....

You will need a bit of software so you can share your Serial NMEA input between both OpenCPN and PolarCom, but either VSPE or NavMonPC can do this.

You can arrange the instruments "around" your OpenCPN window so it looks pretty good.

Re: UTC vs Local Time - Dashboard

Understood, thanks for the replies all.

The problem is, the time in the corner for Windows is sooooo darn small! My old eyes can't see that anymore, especially when I am looking across the bridge at the screen for example. That's why I like the Dashboard with the character font nice and big! At a quick glance I can see, for example, Time To Go: 1:45 and then right there I can also see Time: 17:45. Speed, COG, and Time, nice and big on the Dashboard. (And yes I realize ETA is available when running a Route, but often I don't use that function and just want to quick glance at the basics as I am heading somewhere.
