Help - Clock adjustment

I currently I have a '14 LS460 and my previous car was a '07 LS460. Neither of these cars had an option for "Automatic DST Adjustment." They both require the manual DST on/off operation at the appropriate times. While the TSB that is cited above seems to imply that there is an Automatic DST Adjustment, I don't believe that is the case for the '07 - '14 LS460s. And, these cars require manual entry of the appropriate Time Zone.
I have a 2017 Toyota Sienna that has the option to use either manual DST entry or automatic DST adjustment by applying the DST change convention automatically. There must be some situations where the automatic DST adjustment will not work or there is some concern about the lifetime or stability of the convention making it necessary to provide both options.
It is certainly possible to have radio-controlled timekeeping that considers geolocation and some companies are making wristwatches that have that feature, but your car does not have this feature - correct local time is based on your inputing the correct timezone.
So, "salesguy," it seems to me that your car is fine.
It is possible that my information on this is not correct or incomplete, so I hope we will get some inputs from others to add some clarity on this subject.

2016 recognizes when the car moves into a different time zone, and prompts the driver to accept or not. Analog clock then rolls forward or backwards as required if answered affirmative. kinda cool to watch.

Hey guys, I have a 2013 LS460 and I wanted to make sure I understood the expected behavior.
After the time changed last week, my clock did not. I went into the menu and DST was set to "ON". If I changed it to "OFF" the clock went back an hour.
Am I supposed to have to do that twice per year, or should that happen automatically? I figured that since the car knows where I am it could manage to determine what the time should be.

Interesting. I emailed the Lexus dealer and they seemed to think otherwise - that the DST change should happen automatically. I'd hate to waste time going in and having it worked on if it's not broken.
If you read the TSB it implies that with DST "ON" it should adjust automatically.
Does anyone have a clock that did automatically adjust?

Mine has never adjusted automatically with the "on" set.

Just disconnect the battery for 5 min and reconnect, should be able to set after that. I was having the same problem and cutting the power to the car did the trick.

The lexus master tech confirmed with DST set to "ON" it should automatically correct. The TSB for 2013 confirms that.
From the lexus tech:
The LS clock is set to GPS so it's automatic. The DST is a manual option but when it's selected the clock automatically adjusts. It's a known issue and the TSB replaces the clock.

Mine has never adjusted automatically either, and it's a 2015.

Mine did not adjust automatically either, regardless of whether the DST was set to ON or OFF. When I enter the menu and change the setting, it's fun to see the clock roll back or forward an hour. It worked this way on the 2012 SWB I had last year and my current 2014 LWB.

Interesting. I'm not making a special trip for this work, but on the next service I'll have them do the TSB work. Might be a few months but I will report back.
Maybe there is an issue with multiple years beyond just 2013, or maybe the Lexus guy is wrong.

According to the TSB, the problem clocks would not adjust to display correct time even after manually selecting DST option. My car doesn't have that problem, so I doubt the TSB would be expanded.

That's not what the TSB says actually. 2 conditions may exist to trigger the TSB replacement. #1 is what I'm talking about - which is not automatically updating the clock when DST is set to on. Take another look at the TSB and let me know if I'm mis-reading it, but it seems pretty clear to me:
• Clock will NOT automatically update for daylight savings time (with “Daylight Savings Time”
set to “ON” in the navigation screen menu).
• Clock will NOT automatically update for daylight savings time (with “Daylight Savings Time”
set to “ON” in the navigation screen menu).
