Shell Programming and Scripting

I need to be able to identify files with file timestamps greater than a given timestamp.

I am using the following solution, although it appears to compare files at the "seconds" granularity and I need it at the milliseconds. When I tested my solution, it missed files that had timestamps greater than the given timestamp, but had the same "seconds" as the given timestamp.

Code:

#!/bin/ksh
 
DT_TMSTMP='2012-04-10 08:39:17.807192000'
 
touch --date "$DT_TMSTMP" ./last_date
for i in `find $INFA_SHARED/SrcFiles/NANTEST/Src -newer ./last_date`
do
  print $i
done
exit

It missed these three timestamps:

Code:

08:39:17.861192000
08:39:17.943182000
08:39:17.967204000

and picked up files starting at:

Code:

08:39:18.019186000

Do I have any options to fix this?
Thanks

Looks like your system doesnt support high resolution time...

Does your filesystem even keep an accuracy of nanoseconds for modification times? Most only store them in epoch seconds.

I am able to issue the command ls --file-time and get the full file timestamp, so I believe the filesystem supports it, but maybe (find -newer) does not?
