problem with date in netCDF file

[Don Hooper]

The sdfopen command deduces the increment from the first two time
steps.  It reads none of the other time values.  It presumes it is
a continuous time series.  Thus, it will think that the time value
following any given time step is one interval size later only.  Gaps
will not be handled correctly.  I don't know what to suggest for you,
other than splitting the file up into multiple files at the gaps in time.
