source: trunk/FACT++/src/DataWriteFits2.cc@ 16388

Last change on this file since 16388 was 16097, checked in by tbretz, 12 years ago
Fixed handling of fTstart/fTstop; the start time is now available in the run header and they are both properly initialized so that no nonsense can be written when the file is closed.
