OUTNAME                            Output UV file name (name)
OUTCLASS                           Output UV file name (class)
OUTSEQ           -1.0     9999.0   Output UV file name (seq. #)
OUTDISK           0.0        9.0   Output UV file disk unit #.
REFDATE                            Reference date. 'yyyymmdd'
FQCENTER                           >= 0 -> center frequency axis

HELP SECTION

FXTIM
Task:  This task will read a uv data set to find the lowest time.  If
       that is less than zero, it will change the start date and adjust
       all times while copying the data.
Adverbs:
  INNAME.....Input UV file name (name).      Standard defaults.
  INCLASS....Input UV file name (class).     Standard defaults.
  INSEQ......Input UV file name (seq. #).    0 => highest.
  INDISK.....Disk drive # of input UV file.  0 => any.
  OUTNAME....Output UV file name (name).     Standard defaults.
  OUTCLASS...Output UV file name (class).    Standard defaults.
  OUTSEQ.....Output UV file name (seq. #).   0 => highest unique
  OUTDISK....Disk drive # of output UV file. 0 => highest with
             space for the file.
  REFDATE....Desired reference date 'yyyymmdd' ('dd/mm/yy' accepted
             but deprecated),  ' ' => header value
             The minimum of REFDATE (wrt header date) and the minimum
             time in the data set wrt header date will be used to set
             a new date.
  FQCENTER...>  0 => Change frequency axis reference pixel to
                     Nchan / 2 + 1
             else => do not change reference pixel
