User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:31.0) Gecko/20100101 Firefox/31.0
Build ID: 20141125031119
Steps to reproduce:
Computer (windows 7 pro, 64 bits) is using Europe/Zurich timezone.
With Firefox 49, for the date 04.04.1986 00:00:00.00
new Date(1986, 3, 4, 0, 0, 0, 0).getTimezoneOffset()
Actual results:
returns -60
Expected results:
Expected offset is -120
This is what Chrome returns, and this seems OK because in Zurich, Daylight Saving Time was applied since 30.03.1986 : http://www.timeanddate.com/time/change/switzerland/duebendorf?year=1986
