:: ============================================================
:: time-sync-agent.bat
:: NTPsecDispatcher Windows launcher
::
:: Pings candidate pools, picks the first reachable one,
:: then launches dispatcher.py with --mode and --pool args.
::
:: Usage:
::   time-sync-agent.bat [--mode=fast|ultrafast|lazy] [POOL_OVERRIDE]
::
:: Requirements:
::   - Python 3.9+ on PATH  (or set PYTHON_PATH below)
::   - dispatcher.py in the same folder as this script
::   - Administrator privileges for W32Time configuration
::
:: NOTE: W32Time does NOT support NTS. Use the Unix client for NTS.
