The current date version in Ubuntu 26.04 has an issue where it drops the leading zeros in the nanosecond field before truncating it for %3N. This causes the timestamps of packets to be off for test "IGMP/MLD querier per-port query fan-out interval cadence".
Issue with "date" is recorded at https://github.com/uutils/coreutils/issues/15697 Until Ubuntu picks up a version with the fix, pass only the whole second part of the timestamp to date -d and create the fractional second manually.
