Returns a structure containing time zone information for the machine on which this function is executed. The structure contains four elements with the following keys.

• utcTotalOffset -- total offset of the local time in minutes from UTC (Universal Coordinated Time). A plus sign (+) indicates that a time zone is west of UTC, such as all of the time zones in North and South America. A minus sign (-) indicates that a time zone is east of UTC, such as the time zones in Germany.
• utcHourOffset -- offset in hours of local time from UTC.
• utcMinuteOffset -- offset in minutes after the hours offset is taken into account. For North America, this will always be zero. However, for some countries that do not land exactly on the hour offset, the number will be between 0 and 60. For example, standard time in Adelaide, Australia has an offset of 9 hours and 30 minutes from UTC.
• isDSTOn -- True if Daylight Savings Time (DST) is on in the host machine; False if DST is off.
