Description:
------------
The function strtotime() is really useful.
But it always returns the minimum timestamp that match the input string. It should be even more useful to have a function strtointerval that return a two timestamps: the minimum timestamp that match the input and the maximum one.
For example:
- strtointerval(?Dec 3 2004?) should returns a minimum timestamp (0:0:0 Dec 3 2004) and a maximum one (23:59:59 Dec 3 2004). 
- strtointerval(?Dec 2004?) returns 0:0:0 Dec 1 2004 and 23:59:59 Dec 31 2004
- strtointerval(?2004?) returns 0:0:0 Jan 1 2004 and 23:59:59 Dec 31 2004
And so on.

It should be also useful that strtointerval() parse English sentences like ?between A and B? or ?[form] A to B? where A and B are two valid input for the actual strtotime().

I guess that starting from the source code of strtotime() it should be not difficult to implement strtointerval(), perhaps through a function strtoMAXtime() that generate the maximum timestamp instead of the minimum one, and then adding the English interval sentences support.
