Hi Joshua,

I don't think you should be using file record IDs when you update 
records  using Z39.50. it's true that when you use file record IDs from 
the command line, one way of doing so is to run the zebraidx command on 
a whole directory, and it will compare the time stamp of each record 
against what it holds internally and update only those that have been 
changed..

However, when you are updating the database remotely, you are explicitly 
feeding Zebra with the records that need to be inserted or modified. 
File record ids don't work because no files are involved in the transaction.
