How does UTC time work with daylight savings?
The switch to daylight saving time does not affect UTC. In short, the local time is advanced one hour during daylight saving time. As an example, the Eastern Time zone difference from UTC is -4 hours during daylight saving time rather than -5 hours as it is during standard time.
How do you convert local daylight savings time to UTC?
To convert 18:00 UTC (6:00 p.m.) into your local time, subtract 6 hours, to get 12 noon CST. During daylight saving (summer) time, you would only subtract 5 hours, so 18:00 UTC would convert to 1:00 p.m CDT. Note that the U.S. uses a 12-hour format with a.m. and p.m. Other countries use 24-hour time.

Is DST a time zone?
Most of the United States begins Daylight Saving Time at 2:00 a.m. on the second Sunday in March and reverts to standard time on the first Sunday in November.

UTC time is the local time at Greenwich England. Time in other locations will be the UTC time hour plus or minus the local Time Zone. Daylight savings time adds 1 hour to the local standard (real) time. Twenty four hour time does not use “am” or “pm”, but courts hours from midnight (0 hours) to 11 pm (23 hours).

How to Set TimeZone and DST in x86?
IMO, any use of TurboC localtime (), mktime (), struct tm.isdst field and _daylight will all yield unsatisfactory results concerning daylight savings time and likely be an endless source of timezone issues. Either use a modern compiler/library or import/roll your own (ugh) timezone/daylight routines.
Which is the correct time CDT or CST?

Are there any clocks that do not change with DST?
There are a large number of non-radio controlled clocks, marketed under names like “AUTOSET” or “SMARTSET” that have internal firmware that automatically changes the time by one hour on the transition days to and from DST. These clocks do not connect to a NIST time service, and some of them will no longer work properly due to the DST rule change.
