I just added a fmt="yyyy" to the Time column. This tells the IDV that 
it is the time field. The "yyyy" just parses the 0s in the data 
as the year 0.  
Latitude Longitude magnitude Time[fmt="yyyy"] Altitude[unit="ft"]

The IDV won't automatically recognize the .txt extension as Text Point Data
so make sure you change the "I'm Feeling Lucky" to Text Point Data.

Also, currently we cannot read in the text point data as a aircraft track.
You can however show this with the point data display and turn off decluttering.
We will be adding this feature in the near future though.

Also - we have just written a preliminary help page on this format:
http://www.unidata.ucar.edu/software/idv/release/nightly/docs/userguide/data/TextPointData.html
We will also be adding to it.

I am in the middle of enhancing the capabilities and performance of the text 
point data
files (literally, this morning) so if you have any feedback or requests please
send them in.

-Jeff
