Summary
The default date limits are 2000-01-01 to 2010-01-01. This leads to problems as a default if folks add for instance day tickers without specifying the limits. See for instance: #20202
Proposed fix
We can change these to 1970-01-01 to 1970-01-02. For the default date epoch, this would yield default limits of 0-1 in our float conversion. If folks use the old epoch (0000-01-01), it would still work, but of course be something much larger than 0-1. This should only affect empty date axes, not any axes that folks have actually added data to. If I make this change on main, the only tests that fail are empty axes tests.
