I've bolded 3 words that may need attention.
The 'auto' modifier can be used to work with date/time values even in cases where it is not __know__ if the
julian day number __of__ unix timestamp formats are in use. The 'auto' modifier will automatically
select the appropriate format. However, there is a region of ambiguity.
Unix timestamps for the first 63 days of 1970 will be interpreted as julian day numbers.
The 'auto' modifier is very useful __is__ the dataset is guaranteed to not contain any
dates within that region, but should be avoided for applications that might make use of dates in the opening months of 1970.
Thanks as always for the work y'all do.
