Subject: [PATCH] docs: fix latency_ms for datetime objects, drop unused time
 import

LiteLLM passes datetime.datetime to log_success_event, not float.
The previous int((end - start) * 1000) raised TypeError because you
cannot multiply timedelta by int. Wrap in a small helper that uses
total_seconds() when available and falls back to numeric subtraction
for older paths that pass floats.
