Region and Time: Manually: This is not a valid time (Apple Safari)
Apple Safari 13 gives me ‘This is not a valid time’ (macOS Language: Germany, macOS Region: Germany, Foris 100.7: English or German). reForis works. Mozilla Firefox 72 (on a different computer) works.
WebKit based browser (WebKitGTK 2.26.2):
Firefox 68.4.2esr:
Vivaldi (2.10, Chrome/79.0.3945.94)
The culprit is probably here: https://gitlab.labs.nic.cz/turris/foris/foris/blob/master/foris/static/js/parsley.foris-extend.js#L93
Pure JS Date.parse()
is not reliable cross-browser solution.
