The timezone offset in effect on Dec 25, 1995 won't be applicable in years far away from 1995 (e.g. year 1111). Calculate the timezone offset in Feb 1, 1995 and run other tests on the same day. This issue has been hidden because the current implementation doesn't take into account the history of timezone offset changes(crbug.com/3547), but was exposed when a correct implementation based on ICU was tried. ( https://chromium-review.googlesource.com/c/v8/v8/+/572148 ).
