Find Nearest Date / Time.

General
1

I have lines of text that begin with a time stamp

The digit after the comma is milliseconds.

I want to search through (the dictionary) and find the nearest time stamp that matches my ‘current’ time.
There may be more than one match.

2

I’ve written a class that inherits from Date and adds a property called milliseconds…
How do I write a comparison operator for the class?
i.e. > = <

3

Dictionary may be wrong data structure for this.
Sounds more like a binary search in an sorted array of timestamps.

See Operators
http://documentation.xojo.com/index.php/Operator_Compare

if time and date are equal, compare microseconds.

Simply place all these extended dates together with the current time in an array and sort it. The closest will automatically be next or before.
