Material-ui: [DatePicker] Missing/duplicate days

Created on 15 Oct 2016 · 5Comments · Source: mui-org/material-ui

Problem description

Only on Firefox, day 2016-10-16 is missing and day 2016-10-15 is duplicated. Actually, it seems like the October month, in every year, has a pair of missing/duplicate days. Examples:

Link to minimally-working code that reproduces the issue

Well, you can just go to http://www.material-ui.com/#/components/date-picker and check it out. Remember to test on Firefox.

Versions

Material-UI: 0.15.4, but as you can see the website is also bugged
React: 15.3.2, but the website...
Browser: Tested on chrome and firefox, only firefox has problems. Chrome works correctly.

Hi @xrash, I've not been able to reproduce this. Latest version of Firefox in Mac in this URL http://www.material-ui.com/#/components/date-picker.

Hey @jmansor, you are correct. I am also not able to reproduce this bug anymore. However we can travel time and reproduce it in the past. :)

Change your system time to 2016-10-15 and test it again.

It seems like the bug has some relation with the current date, so it will not happen everyday. I didn't find a pattern, I just know it happened at 2016-10-15 (and some days before that).

Obs: I'm testing on Arch Linux.

Interesting, I am still not able to reproduce it, even by changing the system date. Seems like it's just narrowed to Firefox in Linux. I've tried in Firefox in Windows and Mac but could not reproduce it. Will try in Linux.
