Converts the time value supplied as argument to UTC (Coordinated Universal Time). The function takes the timezone component (for example, "+5:00") into account.
Built-in, C++, C#, Java.
Provides the xs:dateTime value to be converted.
If the input value is 2001-12-17T09:30:02+05:00, the function's result is 2001-12-17T04:30:02.
If the input value is 2001-12-17T09:30:02Z, the function's result is 2001-12-17T09:30:02. In this case, no conversion has taken place, because the trailing "Z" already defines this time to be "Zero" (or "Zulu") time, which is the same as UTC.
