2.2.2 [DOM Level 2 - Core] Section 1.1.6, The DOMTimeStamp type
The specification states:
•Type Definition DOMTimeStamp A DOMTimeStamp represents a number of milliseconds. IDL Definition typedef unsigned long long DOMTimeStamp; •Note: Even though the DOM uses the type DOMTimeStamp, bindings may use different types. For example for Java, DOMTimeStamp is bound to the long type. In ECMAScript, TimeStamp is bound to the Date type because the range of the integer type is too small.
MSXML3 and MSXML6
The DOMTimeStamp definition type is not defined, and there are no APIs that use parameters related to the DOMTimeStamp.
