find on WSL doesn't support time units:

So, to make Homebrew work correctly with both GNU and BSD versions of find, instead of

find ... -mtime -300s

we can use -newermt option, which is supported by both versions of the find command:

find ... -newermt "-300 seconds"

Update 1: Converted to DRAFT for now because WSL treats numbers as "hours", not seconds
Update 2: find on macOS supports -newermt, which is also supported by GNU find. So, updated the PR to use -newermt

Is this dependent on the distribution used in WSL? Can I see your brew config here @maxim-belkin?

I'd like to see confirmation from someone that this still works on ancient Linux/macOS versions that we support (CC @EricFromCanada and @Bo98 who tend to be able to help with these sorts of things).

Sure.

The man page for find on OS X 10.11 includes mention of -newerXY, where X is [aBcm] and Y is [aBcmt].

I noticed this as well on ubuntu/debian and was going to make the same PR 😄

Looks like GNU find's -newermt was implemented back in 2007 (released in 4.3.3): https://git.savannah.gnu.org/cgit/findutils.git/commit/?id=7102a229fa068e5de206cbd0ef1c96decd672c23

And confirmed in ubuntu 12.04 + debian 9.0 (oldest images my docker version can still run):

$ docker run --rm ubuntu:12.04 find /root/.bashrc -type f -newermt "-13 years"
/root/.bashrc
$ docker run --rm debian:9.0 find /root/.bashrc -type f -newermt "-15 years"
/root/.bashrc

I checked back and it seems like it was added on the macOS side back in Mac OS X 10.2.

Thanks for checking all and for the PR @maxim-belkin, great work!
