Wikipedia describes this usage.

ETA is also used metaphorically in situations where nothing actually moves physically, as in describing the time to complete a certain task (e.g. an assembly part and a meeting part). Work undertaken by an individual; a computation done by a computer program; or process undertaken by an organization). The associated term is “estimated time of achievement”, which may be a backronym. For example, Bittorrent clients specify ETAA as the expected time remaining for a file to completely download as 1d4h (1 day and 4 hours), 1w2d (1 week and 2 days), etc.

I personally use and hear it subsequently quite a lot, and it’s quite common in technologic application in terms of down/Uploading files in terms of the

cellular applications. I suppose even a very simple way, but it’s very important, will put very much more effort in making it sound good; just make it sound good.
