what does this mean? (cm related)

I've been a member of CM for a long time, but do not know what everyone means when they say ETA.

ETA has always meant estimated time of arrival to me

I always wondered, but I'm too lazy to look it up. LOL!

Thanks for the responses.

thanks everyone... just wanted to make sure.  I've seen a few use it in place of i.e. or e.g. so was just curious.
