Default Automatic daytime clock change did not work

Can somebody help with my 2011 RX450h, the auto-setting ON for daytime clock in the NAV system did not change the time back to astronomical time? How I can remedy that, In tried turning Off/On in the NV screen but still do not work changing the clock back to a PST astronomical time?

The DST setting of "On" is not DST "Automatic On", it is just Daylight Savings Time is turned On for the season.
A few newer Lexi have the third setting: On / Auto / Off.

Thanks for clarification. Some also said that turning in 2011 RX 450h NAV DTS off will allow my summer daytime saving time to go back one hour? I’ll try and report back. Appreciate any personal experience on this one feature, since it’s not the most intuitive and user-friendly, causes confusion.

You have to change it manually then I think hit save it before leaving that screen.

Yes, you’re right, thank you. I manually turned off the auto-DST and the clock automatically went one hour back, so in March my PST I should again manually to turn this clock feature back to automatic setting in order to change one hour ahead.
