difference between getTime and valueOf

[bottecchia]

Hi,
excuse me for the simplicity of my question, but I'm a beginner..
I've read the methods of the class Date and I've seen that both getTime and valueOf return the time in milliseconds since 1970. Is there a difference? When have I to use one or the other?
Thanks in advence!

If you view the web page listed above the valueOf method returns "the primitive value of a Date object". That is kind of a vague description of the method, and I would not expect it to behave the same on all platforms. However, the getTime method returns "the number of milliseconds since midnight Jan 1, 1970" - that is a pretty clear-cut definition and seems that it would be a lot more reliable on multiple platforms.

Personally, I always use getTime().
