There is!
SLEEP
If you want it in millisecond mode:
SLEEP -m
This is more helpful than TIMEOUT because TIMEOUT can be aborted with a click of a key or CTRL + C (for TIMEOUT /t /nobreak). SLEEP cannot be aborted by anything (except for close button :p)
Other one is PING. But PING needs internet connection because you'll be recording the connection of a site.
