Not really. The same effect cannot be achieved with logrotated, only an
approximation based on a sudden rush to rename several log files all at
midnight.

The logs could go into per-day files and merged into a monthly file daily, but
that makes the current file more difficult to tail -f.

It could be quite complex to add strftime without making it less efficient; the
whole format string can't be passed to strftime because it will have a %s in
it.
tod_stamp() would need to gain a format string parameter which is then only
used by some callers, or all callers would have to pass a format string and use
strftime() instead of sprintf().
