Expected behavior

Time remains correct relative to host. This has been discussed already in #72

Actual behavior

During sleep, Docker Hyper-V VM slowly drifts out of sync with host time.

Information

The problem appears to be a re-emergence of #72. Another individual posted a similar comment at the end of #72. It appears to happen reliably during sleep. It only ends up being important when things happen that require time to be coherent with the real world. For example, this can mess up apt update.

• Windows Version: 10 Pro 1903
• Docker Desktop Version: 2.1.1.0

Steps to reproduce the behavior

1. Run Docker for Windows
2. Sleep the machine for a while
3. Observe that time gets out of sync

You can check time on the Docker VM like:

docker run -it --rm ubuntu:18.04 date

You can get UTC on Windows PowerShell like:

$Time = Get-Date
$Time.ToUniversalTime()

There is a small chance that this is affected by setting the Windows hardware clock to UTC (which I suspect many Docker users do - since it makes dual-booting linux easier) [per @echadwickb's comment below]
