CST is Central Standard Time. CDT is Central Daylight Time. CT is Connecticut, but some people mistakenly use it as an abbreviation for Central Time. Daylight Saving Time begins and ends on dates set by law. Nationally, in 2012, it begins on March 11 at 2:00am and ends on November 4 at 2:00am, but states and regions may or may not choose to go along, so it is very important to use the full three letter abbreviation. Use CST when referring to time in the central time zone when and where Daylight Saving Time is not in effect. Use CDT when referring to time in the central time zone when and where Daylight Saving Time is in effect. Use CT to refer to Connecticut, or any number of other things abbreviated CT, but NEVER to identify a time zone, unless your goal is to confuse people.
Use CST (Central Standard Time) when referring to the time in the Central Time Zone when Daylight Saving Time is not in effect. Use CDT (Central Daylight Time) when Daylight Saving Time is in effect in the Central Time Zone. Use CT as a general abbreviation for Central Time without specifying whether it is standard or daylight time.
CDT means Central Daylight Time while CST means Central Standard Time. The difference is that CDT is used while Daylight savings is in effect, therefore in the summer. CST is used in the winter. In Canadian Providences Ontario (a few communities) and Saskatchewan (most), CST is used all year.

11:59 PM CST = 12:59 AM EST11:59 PM CDT = 11:59 PM ESTExample: During the summer, the time is the same in Chicago (CDT) and Jamaica (EST).

Its GMT -5 hrs. CDT = GMT-5 hrs (i.e. if its 18:00 hrs @ GMT then it would be 13:00 hrs @ CDT) CDT stands for Central Daylight Time. Its basically Daylight Saving Time (DST) for Central Time (CT) which is applicable or get activated during summers only. You can say that CDT is the summer time zone for CT. Normally CT is GMT-6 hrs but due to this daylight saving it becomes DST @ GMT-5 with the saving of 1 hr. After the Summer months Central Time is shifted back by 1 hour to US Central Standard Time (CST) or (GMT-6). Regards Chander Sangra
Yes, Adelaide is in CST/CDT (the part of the Central Time Zone that observes Summer Time from October 'til April).
Chicago was on Central Daylight Saving Time (CDT) 28 April 1957 - 27 October 1957.
3 am PHT (Reminder: There is no part of the U. S. that uses CST between March and November. CST is the same as MDT, which is used in the U. S. during that time, and areas that are in CST during the winter are in CDT in spring & summer. CDT is an hour closer to Philippine Time than CST.)
Mountain Daylight Time (MDT) is 1 hour ahead of Mountain Standard Time (MST). Central Standard Time (CST) is 1 hour ahead of Mountain Standard Time (MST). So CST would be the same time as MDT. However, This would only occur for 1 hour during Autumn when CDT falls back to CST and MDT hasn't yet fallen back to MST.
In North America,0930 EST = 0830 CST = 0930 CDT = 1030 EDT, and0930 EDT = 0730 CST = 0830 CDT = 0830 EST.In Australia,0930 EST = 0900 CST = 1000 CDT = 1030 EDT, and0930 EDT = 0800 CST = 0830 EST = 0900 CDT.Examples:In June, when it's 0930 EDT in New York, it's 0830 EST in Jamaica, 0830 CDT in Chicago, and 0730 CST in Guatemala.In December, when it's 0930 EDT in Sydney, it's 0900 CDT in Adelaide, 0830 EST in Brisbane, and 0800 CST in Darwin.
