[kronolith] event_id and event_uid

[Achim]

Hi,
I want import some event from a other database automaticly by using a 
small script. This should insert the events directly into DB tab 
knonolith_events

Now I try to understand the syntax from event_id and event_uid in tab 
kronolith_events. Without success.
I don't find the right lines in sourcecode, too.

Can anybody help me?
event_id = ?
event_uid = <year><mon><mday><hours><minutes><seconds>.<???>.@<domain>

Thanks,
Achim
