Time of contest in 'my timezone' is not displayed correctly

When I open contests page, all times look normal (both start and end):

IST timezone

But if I switch to my timezone all first numbers of hour get shifted to the first line:

My timezone

I still can read them of course but it surely doesn’t look like normal. Am I the only one experiencing such problem? I experience this in both Firefox 65.0.2 (64bit) and Yandex Browser 19.1.0 beta (64bit) on both Arch Linux and Windows 7.
It doesn’t look like a problem on my side (since I see this in different browsers and systems) so I hope codechef team fixes this.
