Some future events are not showing up in Timeline when there are a lot of events

[Google Code Exporter]

What steps will reproduce the problem?
1. Add about 545 events to Simile-Timeline
2.
3.

What is the expected output? All events that fit the timeline query showing in 
the swimlanes.

What do you see instead? Only events two weeks out from the current date and 
within previous year.

What version of the product are you using? How do I find out?

On what browser and what operating system? IE9, Windows 7 Enterprise


Please provide any additional information below.
If I remove some events it shows more events in the future, so a workaround 
would be to remove older events so events more than two weeks out can be shown, 
but we want all events shown that should be shown. 
Every day I see one or more new events two weeks out and the ones older than a 
year drop off. It looks like SPServices in only putting ~545 events in 
json.events.

I discovered SPServices is what was limiting the events on the timeline. I 
added the parameter CAMLRowLimit with a high value and now it is showing all 
the future events. I'd still like to know how to make events older than a year 
show.
