Unix Timestamp & Epoch Converter
Convert Unix epochs (seconds, milliseconds, microseconds) to ISO-8601, RFC-2822, and human-readable UTC/local dates with instant leap second and timezone handling.
Epoch to Calendar Date
Paste or type any integer or float epoch. Automatically identifies standard seconds, milliseconds, or microseconds.
Calendar Date to Epoch
Specify year, date, time components and target timezone to produce POSIX integers and hexadecimal timestamps.
Batch Stream & Server Log Translator
Paste server logs, CSVs, or multi-line epoch lists. In-place regex substitution replaces 10-16 digit timestamps with human ISO/Local format.
Year 2038 Milestone
32-bit signed integer timestamp overflow limit (2,147,483,647). Systems must migrate to 64-bit integer timestamps to prevent negative epoch wraps.

Inspect and decode JSON Web Tokens locally. Parse exp, nbf, and iat epoch timestamps into readable dates.
Generate cryptographically secure monotonically sorted identifiers with embedded Unix epoch millisecond headers.
Design schedule expressions with instant next 10 executions preview and human English recurrence explanations.
