Detailed Description

Generated unique IDs.

Creates (somehow most of the time) unique IDs from a given prefix, the current date/time and a random part.

The prefix is given to the constructor, together with the desired length of the random part (minimum 5 digits).

The current implementation uses the time in seconds in combination with an a random part. This should assure a unique ID on a very high probability. Still, there is a very small chance to get identical random numbers. A feature request for improved UID generation is handled in BUG 14333.
