Bring dpll monitor in line with the rest of iproute2 by allowing each received notification to be prefixed with a wall-clock timestamp. -t / --timestamp emit a separate "Timestamp:" line before each event, using the default text form of print_timestamp() (matches ip / bridge / tc -t monitor) --tshort emit a compact ISO 8601 prefix "[YYYY-MM-DDTHH:MM:SS.uuuuuu]" inline instead (matches ip -ts monitor) When combined with -j, the timestamp shows up as a "timestamp" / "timestamp_short" field on each notification object, the same way ip -j -t mptcp monitor integrates the helper. The flag is parsed globally but only consulted from the monitor callback, so passing -t to non-monitor commands is a no-op. --tshort has no short alias, so its long_options entry uses an identifier above the ASCII range (OPT_TSHORT = 256) following the iproute2 convention used in misc/ss.c, instead of consuming an ASCII letter that could later collide with a real short option.
