- * 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.
