UTC time (universal time convention) is used in ANSI-C standard for defining time. This is measured in seconds since 1970, at the Prime Meridian. By definition, UTC does not depend on Daylight Savings Time. The UTC_TIME function uses a C-MEX function to get the System Time in UTC format.
Another function UTC2DATENUM will convert any UTC time to the correct MATLAB serial date number in local time, accounting for Daylight Savings. This is done with the help of the C-function gmtime. Vectors are supported. The difference of the local time from UTC is also provided as an output.
