Convert Seconds to Timestamp

If you have a list of seconds since 1970-01-01 00:00:00 UTC, and you need to know what actual timestamps they represent, this tool gives you instant results. The Convert Seconds to Timestamp tool takes each input, treats it as a Unix timestamp in seconds, and converts it into a readable full UTC datetime like 1970-01-01 00:00:42.

This is especially useful when reviewing system logs, working with databases, or converting values from APIs that provide time as raw epoch seconds. You paste your seconds in, and the results update live. No server-side processing. No setup. Just clean, readable UTC output.

The tool supports decimal input, skips invalid lines if desired, and gives you a complete formatting suite including file import, copy, export, and auto-cleanup options.

How to Use:

• Paste or type one number per line into the Input Seconds Since Epoch field.
• Each number is treated as seconds since 1970-01-01 00:00:00 UTC.
• Use the Trim input lines toggle to clean up pasted spacing.
• Turn on Ignore invalid entries to skip non-numeric or negative lines.
• Use Maximize output to expand the results box.
• Output updates live click Convert if you want to trigger manually.
• Click Copy Output to copy the results (you’ll see “Copied!” flash).
• Click Export to File to save the converted timestamps as .txt.
• Click Choose File to import values from .txt, .csv, .log, or .json.
• Click Clear All to reset everything: input, output, toggles, file, and counter.

What Convert Seconds to Timestamp can do:

This tool turns epoch seconds the standard for timestamps in most APIs and systems into full human-readable timestamps in YYYY-MM-DD HH:MM:SS format. Each second value gets converted into a date and time, normalized to UTC. For example, entering 0 gives 1970-01-01 00:00:00, while 86400 gives 1970-01-02 00:00:00.

The output is ideal for debugging, analysis, and data cleanup. Whether you’re reviewing log events, aligning timestamps in Excel, or parsing raw values from backend storage, this gives you clarity without needing shell commands or scripting.

You control the format and the cleanup. Invalid inputs like not-a-number or -100 show as Invalid unless you tell the tool to skip them. Every valid result is shown with zero-padded formatting, making it easy to sort or match.
