I’m running Local on a Mac and have noticed that the clock on my Local sites slowly falls behind. I think the issue is related or similar to the issue described in this GitHub issue https://github.com/docker/for-mac/issues/17
Briefly, the issue appears to be that the Linux VM, within which the Docker containers run, doesn’t track time properly. The containers adhere to their parent OS’s time (which is not my Mac, but the Linux VM) and so the containers slowly fall behind.
As I am using some time-sensitive applications, I am having to restart my Local Machine on a regular basis.
NB: I have applied the fix outlined in the above GitHub page, but it has not resolved the issue.
