I think this is wrong. Datetime storage may be int, but since they're
microseconds underneath, we'd be unable to specify a full-resolution
timestamp if we didn't have float ms or integer µs. So either the
seconds argument should allow fractions (probably not a good idea), or
we should have another integer argument for microseconds (not
milliseconds as the above signature implies).
