+ * Google Chrome as of 67.0.3396.87 introduced timezones with offset that includes seconds.
+ * They usually appear for dates that denote time before the timezones were introduced
+ * (e.g. for 'Europe/Prague' timezone the offset is GMT+00:57:44 before 1 October 1891
+ * and GMT+01:00:00 after that date)
+ *
+ * Date#getTimezoneOffset returns the offset in minutes and would return 57 for the example above,
+ * which would lead to incorrect calculations.
+ *
+ * This function returns the timezone offset in milliseconds that takes seconds in account.
