Timestamps in API testing
API responses frequently include timestamps as Unix seconds or milliseconds in fields like created_at, expires_at, and last_login. Converting them quickly helps you verify that expiry windows, rate limit resets, and scheduling logic are correct during manual investigation.
JWT tokens use Unix seconds for exp and iat claims. Paste those values here to instantly see when a token was issued and when it expires, without doing mental arithmetic.
