Fixing the design: In various part of the FireVoxel there is an inconsistent treatment of time values.  Certain structure hold time in "Absolute format" (i.e. seconds since Jan 1, 1900), other structures keeps them in seconds since the start of acquisitions.  This causes several glitches, f.e. during transfer of the Input function, from Automatic IDIF finder into Parametric Model calculation model.
Presently converting all the internal structure into the "Absolute format".  Relative times would only be constructed temporarily for specific purposes such as Display and during the Parametric Model calculations.
