PDL::DateTime is a subclass of PDL piddle for storing date-time values (scalar piddles, vectors, matrices or generally ND-piddles): - its PDL type is always LongLong (64-bit signed integer) - stored values are microseconds since 1970-01-01T00:00:00.000000Z (can be both positive or negative) - it is still a piddle so you can do all usual PDL arithmetic + PDL::DateTime defines some new methods (see below)
