6250 +accelerometers to TDMS files - timing calculations?

Is there a way to calculate time differences in TDMS files between a set of 5 accelerometers and when they activate? Our set up is:

1. Meggitt accelerometers 5 pieces - 2255B model
2. NI PCI 6250 data acquisition board
3. Driver package – NDQX 9.5.3
4. Software settings are: sample record 1024; channel gain 50; Trigger level 1; samples per second 2000; trigger delay 500
5. TDMS file generated

So, we can count the cycle differences in the waveforms. Can they be calculated back to time so we can get time differences. Any ideas?
