There was a problem hiding this comment.
This is unusual, because jest's expect matchers don't work properly with Invalid Dates.

In retrospect, I'm unsure if using a string instead of an int in the array shape causes a performance hit. Invalid Dates may deserve their own type, but I'll leave this PR as-is. |

Invalid dates currently throw a SyntaxError during decoding, because
new Date('invalid').getTime()returns NaN, which is invalid JSON.I wasn't sure how you'd like to encode this, so I just created the test.
