Ah, sorry, I added timestamping output as a local patch for NIPA.

Random example:

TAP version 13
1..1
# overriding timeout to 7200
# selftests: net: amt.sh
# 13.15 [+13.15] TEST: amt discovery                                                 [ OK ]
# 16.27 [+3.12] TEST: IPv4 amt multicast forwarding                                 [ OK ]
# 19.14 [+2.86] TEST: IPv6 amt multicast forwarding                                 [ OK ]
# 670.88 [+651.74] TEST: IPv4 amt traffic forwarding torture                           [ OK ]
# 1203.28 [+532.40] TEST: IPv6 amt traffic forwarding torture                           [ OK ]
ok 1 selftests: net: amt.sh

It's not great, makes the lines longer and misaligned.
But it's helpful for debugging slow tests.
