processStartTime read `ps -o lstart` in local time and rebuilt it with a
hand-written month table. In the hour that repeats when DST ends, local
01:30 names two instants and the reconstruction picked the first, putting a
backend started in the second 3600 s off its ledger create_time, so a valid
host backend was rejected. ps now renders lstart with TZ=UTC0 and the value
is parsed as GMT with Date.parse (V8 accepts the exact `ps` format,
including the double-spaced day), which also drops the month table.
