No way! Copyright law does not prevent someone from creating a new work that is designed to be compatible with an old work. Likely outcomes are that the poem would not qualify for copyright protection for that usage (it's not a poem as much as a sequence of arbitrary bytes to be read only by a computer), or that a fair use finding would be made, perhaps on the grounds that the copy does not affect the market for the original work - i.e. nobody was paying for the poem. Most likely a judge would just throw out the entire case at the start as a waste of the court's time.
Am I wrong about this?
> ...The ntpd algorithms discard sample offsets exceeding 128 ms, unless the interval during which no sample offset is less than 128 ms exceeds 900s. The first sample after that, no matter what the offset, steps the clock to the indicated time.
> This may on occasion cause the clock to be set backwards if the local clock time is more than 128 [m]s in the future relative to the server. In some applications, this behavior may be unacceptable.
