| description | Use this skill any time the conversation mentions timestamps, durations, "X minutes/hours ago", log timestamps, scheduled tasks, or comparing times from different sources (logs vs wall clock vs API responses). Prevents UTC↔KST confusion that caused a 9-hour misreading on 2026-05-13. |
This user works from Korea (KST = UTC+9). Their Mac local time prints in KST. Most remote servers, log files, HF API, GitHub, etc. print in UTC. Never mix them silently.
