    Unless I am missing something, which wouldn't surprise me in the least, I find it annoying that the two clocks do not sync with each other and that you must manually set the Dashboard Clock. I was somewhat excited when I found clock settings in the navigation screens but annoyed when I noticed it didn't set the dashboard clock which my dealership didn't think to fix before delivering the car to me. Honestly, this was probably a good thing because it would have annoyed me more later than it does right now, as I am sure the clock will drift and at least now I know they aren't in sync rather then thinking they are and finding issues between the two and trying it figure out which button or gadget to monkey with to fix it.

    So am I missing something? Should the dashboard clock be able to be synced with GPS? The manual is pretty skimpy on explaining the dashboard functions.

    What's got your nav so busy that it can't spare a millisecond of its precious time to update the dash clock? ;)

    Perhaps I should clarify, when I say Navigation Clock I should specify that this clock is used for destination time estimates and for the charging calendar features. It is GPS set and can auto adjust to time zones. The Dashboard clock is up in the upper display to the right of the speedometer in with the warning lights. If you allow the navigation clock to adjust by position you will see things like the time to reach a place being off by an hour if you cross timezones because the navigation system will adjust but your display will not. The navigation clock isn't a display clock as far as I can tell, it just manages things like internal calendars in navigation time details. It is also helpful for time of day navigation information which are somewhat predictive and are based on past time of day details.

    That said, it is annoying that such a high tech car doesn't use the very simply time data contained within the navigation feed. Honda vehicles that have navigation have (at least in my experience) set the system clock from this information (at least since 2005 and probably well before).

    Ever since the daylight savings time change I'm having a similar issue and it's kinda annoying.

    My dash clock is correct, but my GPS "time to arrive at destination" is an hour off, just like it never updated from the time change!?

    Does anyone know how to update this GPS "clock"? I sure as heck can't figure it out...

    Thx.

    On the Navigation system, click Settings, then General Settings then System Time. There are three options to adjust within this panel, Timezone, Daylight Savings and GPS Auto Adjust. What is interesting is that the system documentation doesn't tell you if it automatically adjust to daylight savings time on its own with GPS Auto Adjust set. Having not owned the vehicle through a time change yet, I don't know what it will do.

    gotcha. so my nav must have an internal clock? either way, the dash clock loses a minute or two a month, and i have to reset it manually.
    hopefully prime has fixed all that! (but i don't it, there isn't much high tech going on with entune)

    The navigation time comes from the satellite, which has an on board atomic clock.

    So Liskipper, I also am frustrated with this clock set. Have you found the procedure?

    They don't sync. and can't be set to sync. Maybe one day the engineers at Toyota will put it in the standard. They don't actually make either the GPS or the clock.
    All GPS units know the time to nano-seconds. They can even adjust for timezones if the manufacturer bothered. And daylight savings too! What a concept!

    Some parts of our cars are still stuck in the 20th century. ;)

    The system doesn't know it's DST. You have to manually set it twice a year.

    Hopefully soon they will just forget about DST altogether so we dont have to deal with this each year.

    I wish we changed more often.

    Here at work, we use time servers that get their accurate time from GPS. Ideally you should just need to set Timezone & DST values.

    If we did not have DST how would we know when to change the batteries in our smoke alarms?

    On my new Prime, the dash clock is correct (PST, for SF Bay Area), but the navigation screen clock shows expected arrival times 1 hour late. If it thought daylight savings time was in effect, it would be 1 hour early. Obviously the GPS knows both the actual time and the geographic time zone, so I'm surprised such a high-tech machine can't connect the dots, or make the two clocks agree. I also wonder if the navigation system is making proper use of real time traffic updates, when it doesn't know the real time.

    Extracting time zone from a geographic location turns out to be a way harder problem than it sounds like it would be.

    With the PiP, the calendar skips one full day every 4 years! It does not recognize February 29th. Somehow I feel the Prime calendar is the same - let's wait to 2020.

    Cars have gotten so automated nowadays, they needed to give the driver something to do to feel involved so they still let us set the dash clock.
