GetTimeZoneInfo
Description
Gets local time zone information for the computer on which it is called, relative to Universal
Time Coordinated (UTC). UTC is the mean solar time of the meridian of Greenwich, England,
used as the basis for calculating standard time throughout the world.
ColdFusion stores date and time values as date-time objects: real numbers on a universal time
line. It converts an object to a time zone when it formats an object; it converts a date/time value
from a time zone to a real number when it parses a value.
Returns
Structure that contains these elements and keys:
•
utcTotalOffset: offset of local time, in seconds, from UTC
A plus sign indicates a time zone west of UTC (such as a zone in North America)
A minus sign indicates a time zone east of UTC (such as a zone in Germany)
•
utcHourOffset: offset, in hours of local time, from UTC
•
utcMinuteOffset: offset, in minutes, beyond the hours offset. For North America, this is 0. For
countries that are not exactly on the hour offset, the number is between 0 and 60. For example,
standard time in Adelaide, Australia is offset 9 hours and 30 minutes from UTC.
•
isDSTOn: True, if Daylight Savings Time (DST) is on in the host; False, otherwise
