We record data long term on computer using tshark/dumpcap on various windows
machines. 

Sample command line arguments: 

tshark.exe -i\Device\NPF_{EA8B6130-0B39-4670-9339-B5C0889AB68F} -b
filesize:1000000 -b duration:3600 -f "filter here" -w "D:\vcs0\vcs0.cap"

Every hour a new file should be created. Our recordings are always under
filesize:1000000. Sometimes, tshark/dumpcap misses that time and just continues
recording a file until the maximum is reached.

Attached is a screenshot that helps show the situation. Notice most of the
recordings start on the hour exactly. File 395 then misses the close time and
keeps going until it hits the max. After that, the files never use the duration
filter again.
