[Numpy-discussion] datetime64 format parameter?
Mon Feb 6 15:18:57 CST 2012
NumPy doesn't provide this, because it's already provided by the
datetime.date.strftime function in Python:
One reason this format isn't supported automatically is that parsing
"MM/dd/YY" is inherently ambiguous, and the convention is different in
different parts of the world. The date "01/02/03" could be January 2nd 2003
or February 3rd, 2001, for example. The datetime constructor follows the
ISO 8601 standard for date and time formatting, which is unambiguous. This
was specified in the datetime NEP, but the 1.6 implementation unfortunately
hadn't followed that part of the spec.
