What is the expected behavior?

To go to year 2008

DatePicker breaks and skips 2008 and goes to 2007

You can provide an example code that fails here: https://stackblitz.com/edit/dialog-example

It helps the team to better understand your case.

echosalik commented 7 years ago

I'll provide a code soon in an hour or so. And sorry for the closing and reopening. Clicked the wrong button.

echosalik commented 7 years ago

Just noticed something. This doesn't happen on my home computer. Windows 10 64 bit. At work it was windows 7. Could that be an issue?

julianobrasil commented 7 years ago

Did you test it using the same browser in both cases?

@DragoTechInnovations have you been able to get a consistent reproduction of this issue?

echosalik commented 6 years ago

@mmalerba unfortunately no. I guess its related to linux, rather then Firefox or Chrome, because it works flawlessly on windows systems.

mmalerba commented 6 years ago

It seems to work fine on my linux machine. Is there anything notably different about how the date/time settings on the problem machine? (e.g. different time zone or something)

echosalik commented 6 years ago

Well, the timezone and date format is not US. Timezone is Karachi and Format is en-GB.

mmalerba commented 6 years ago

Ah I've managed to reproduce it with Firefox 57.0.1 on Linux with my timezone set to Karachi. Will look into it. I also verified that its only the NativeDateAdapter that has this issue. If you use the MomentDateAdapter it should work fine.

mmalerba commented 6 years ago

Looks like there is a similar breakdown in Kiev timezone around 1975

@mmalerba Thanks, I'll try that on monday and let you know!
