Time interval is specified in the control file used to open the data file. However, if you used xdfopen or sdfopen, there may be a different way to determine the time interval. In those cases, you should be able to find it by dumping the contents. If your data are in netCDF format, for example, you could use ncdump -h (data file) to find out.<div>
