I am confused - the two print outs you sent have identical formats.
All columns line up and the time is in floating days.  I did change the 
task to do pure F formats where possible, doing a serious analysis of 
what format would be required to represent the range of numbers.  NDIG 
of 0 and negative selects this preferable format for human consumption - 
it simply is easier to read quickly.  NDIG > 0 selects all exponential 
format which is easier for software to read.
