Timestamp Converter v1.0.0

Convert between Unix timestamps and human-readable date/time formats. Accepts Unix epoch (in seconds or milliseconds), ISO 8601 strings, or 'now' for the current time. Returns both Unix seconds and milliseconds, ISO 8601 UTC string, date and time components, day of the week, relative time description ('2 hours ago'), and past/future indicator. Auto-detects whether a numeric input is seconds or milliseconds based on magnitude. Essential for debugging logs, API timestamps, cron scheduling, and time zone conversions.
