I haven't really been watching CF-Talk that closely lately, so I may be
missing some info here, but...
If you are in need of a random and unique ID, I would suggest using the
CreateUUID() function, not a timestamp. It is unique across the universe
and is only 35 characters long. Also, if you actually store this as a date
stamp in a database (which I'm not sure you are doing), I recall reading
that SQL 7 (and probably other RDBMS platforms as well) don't store date
stamps with millisecond precision, so the chances of dups would be much
higher.
