See `man vsl`, the second decimal field is the "Time since start of
work unit", so in your case it should be 0.065862 seconds or almost
66ms from the last Timestamp record. But there are other details to
consider, like buffering in your TCP stack, or apparently the lack of
Timestamp record for the response body.
