                                   String prototype)
```
    Returns a format to use for parsing values along the specified axis type. This method is invoked when parsing the date part of axis units like "days since 1990-01-01 00:00:00". Subclasses should override this method if the date part is formatted in a different way. The default implementation returns the following formats:
    - For time axis, a DateFormat using the "yyyy-MM-dd HH:mm:ss" pattern in UTC timezone.
    - For all other kind of axis, a NumberFormat.
    The Canada locale is used by default for most formats because it is relatively close to ISO (for example regarding days and months order in dates) while using the English symbols.
    Parameters:
    
    type - The type of the axis.
    
    prototype - An example of the values to be parsed. Implementations may parse this prototype when the axis type alone is not sufficient. For example the time axis type should uses the "yyyy-MM-dd" date pattern, but some files do not follow this convention and use the default local instead.
    
    Returns:
    
    The format for parsing values along the axis.
  - getCheckType
```
public static NetCDFUtilities.CheckType getCheckType(NetcdfDataset dataset)
```
    Depending on the type of model/netcdf file, we will check for the presence of some coverageDescriptorsCache rather than some others. The method returns the type of check on which we need to leverage to restrict the set of interesting coverageDescriptorsCache. The method will check for some KEY/FLAGS/ATTRIBUTES within the input dataset in order to define the proper check type to be performed.
    
    Parameters:
    
    dataset - the input dataset.
    
    Returns:
    
    the proper NetCDFUtilities.CheckType to be performed on the specified dataset.
