Report #72218

[bug\_fix] RequestExpired: Request has expired. Timestamp is XXX and expiration was YYY \(or SignatureDoesNotMatch: Signature expired\)

Synchronize the system clock using NTP \(e.g., \`sudo ntpdate pool.ntp.org\` or enabling \`systemd-timesyncd\`\). For Docker containers, ensure the container inherits the host's time via volume mount \`/etc/localtime\` or runs an NTP client, or simply restart the container to resync with the host clock.

Journey Context:
A developer runs a long-lived Docker container on their MacBook Pro for local integration testing. The container uses the AWS SDK to call DynamoDB. The MacBook sleeps overnight. In the morning, the container resumes but its clock remains at the time the MacBook slept \(drifted by hours\). The next AWS API call fails with 'RequestExpired'. Checking \`date\` inside the container confirms the lag. Restarting the container fixes it by re-syncing with the host's corrected time. The permanent fix is enabling NTP on the host and ensuring Docker Desktop's time sync is active.
