Windows Docker Update Clock - Shell/Bash

Are you experiencing issues with your Docker containers showing incorrect time? This can become a problem when working with time-sensitive applications or debugging issues that depend on accurate timestamps.

Luckily, there's an easy solution to fix the clock within your Docker containers. We can use the docker run command with the --privileged flag and run a shell script to update the date and time within the container to match that of the host machine.

Here's an example of the shell script:

#!/bin/bash
echo "Setting date and time within Docker container..."
echo "Current date and time: $(date)"
echo "Host machine timezone: $(cat /etc/timezone)"

cp /usr/share/zoneinfo/$(cat /etc/timezone) /etc/localtime
echo "Updated timezone to: $(cat /etc/timezone)"

Steps to use this shell script:

1. Save this code as a file on your host machine, for example, update-clock.sh
2. Run the following command to start a new container with the script mounted as a volume:

docker run --rm -it --privileged -v $(pwd)/update-clock.sh:/tmp/update-clock.sh alpine:latest sh /tmp/update-clock.sh

3. You should see the output from the script, including the current date and time, the host machine's timezone, and the updated timezone within the container.
4. Check the date and time within the container using the date command.

This method ensures that your Docker containers have the correct time, allowing you to work with time-sensitive applications or debug issues with accurate timestamps. Give it a try!
