About this tool

Datetime to Timestamp Converter converts a calendar date, time, and GMT offset into Unix seconds. Use it for APIs, schedulers, reports, and systems that need epoch values.

Input rules

Enter the date as YYYY-MM-DD and time as HH:MM or HH:MM:SS.

Choose the GMT offset that matches the source system, meeting time, or intended clock context.

Outputs

The tool returns Unix seconds plus ISO 8601 and UTC views so the instant can be checked before copying.

info

Gotchas

The timezone offset changes the generated timestamp. If the offset is wrong, the result points to a different instant.

Review the UTC output when the timestamp will be consumed by a system that stores time in UTC.
