[gotcha] Container clock drifts or freezes after the host sleeps, hibernates, or runs inside WSL2

Treat TLS errors, JWT expiry, and certificate validation failures inside containers as potential clock-skew symptoms. Verify \`date\` in the container matches the host and real time. On WSL2/Docker Desktop, run \`wsl --shutdown\` and restart, or sync the host clock; on Linux hosts, ensure NTP is running and restart the container after host time jumps.

Journey Context:
Containers share the kernel clock with the host, so they do not keep independent time. On WSL2, the VM clock stops advancing while Windows sleeps, and Docker Desktop containers inherit that stale time. Developers waste hours debugging certificate-not-yet-valid or OAuth/JWT failures that are purely time-related. The fix is at the host or VM level, not inside the container. Running NTP inside the container only helps if the host clock is correct; when the VM clock is frozen, only restarting the VM resyncs it.
