Class Description

                                                                      
 GPS Time                                                             
                                                                      
 Time defined by GPS standard

const Text_t* ExpressTime(Double_t gpstime, Option_t* fmtopt, Int_t leapS, Int_t local0)

 Given a GPS time, expresses it in a convenient format
 depending on the chosen options for time format in option
 options are  "GPS", "LOCAL", "LOCALEUR", "LOCALUS", "UNI",
  "UNIEUR", "UNIUS"
 If none of these formats is used, the string is interpreted as an
 input string to the standard C strftime function. See TAxis::SetTimeFormat
 for more information.
 ULeapS are the leap seconds needed for the GPS->UTC conversion
 (33 seconds as of 1st January 1999, changes aprox. once per year,
   given by the frames/ vectors)
 local is the difference in multiples of 1800 s between UTC and the local time
 Not used for the time being since "local" means local to the machine
 on which the display is done and not local to the experiment. May change
 in the future but needs to include some info like if there is a daylight
 savings time locally on the experiment.

const Text_t* ExpandFormat(const char* fmt)

 Expands the format fmt, which can be any of
 "GPS", "LOCAL", "LOCALEUR", "LOCALUS", "UNI", "UNIEUR", "UNIUS"
 If none of these formats is used, the string is interpreted as an
 input string to the standard C strftime function. See TAxis::SetTimeFormat
 for more information.
