docker run --cap-drop SYS_TIME myimage

What is the problem and how to fix it?

AProblem: Syntax error in command. Fix: Remove <code>--cap-drop</code>

BProblem: SYS_TIME is dropped, so container can't change time. Fix: Use <code>--cap-add SYS_TIME</code>

CProblem: Container runs with full privileges. Fix: Add <code>--cap-drop ALL</code>

DProblem: SYS_TIME is not a valid capability. Fix: Use a valid capability name

Step 2: Correct the command to add the capability
To allow changing time, use --cap-add SYS_TIME instead of dropping it.
Final Answer:
Problem: SYS_TIME is dropped, so container can't change time. Fix: Use --cap-add SYS_TIME -> Option B
