This inherits from datetime.datetime, so it can use all of the methods

operation are also a Timestamp object, be sure to use only Timestamp
objects (and datetime.timedeltas) in any operation.
Use Timestamp.fromISOformat() and Timestamp.fromtimestampformat() to
create Timestamp objects from MediaWiki string formats.
As these constructors are typically used to create objects using data
passed provided by site and page methods, some of which return a Timestamp
when previously they returned a MediaWiki string representation, these
methods also accept a Timestamp object, in which case they return a clone.
Use Site.server_time() for the current time; this is more reliable
