Convert Timestamp to Seconds

Need to figure out exactly how many seconds are in a given time or date? The Convert Timestamp to Seconds tool makes it simple. Whether you’re working with Unix-style datetimes like 1970-01-01 00:01:00, ISO timestamps like 2024-01-01T00:00:00Z, or just plain timecodes like 00:01:30, this tool breaks it down to the raw second count all in your browser, no page reloads.

It works with multiple formats, updates instantly, and lets you copy or export the results with one click. If you’ve ever needed to line up logs, debug time data, or convert human-readable timestamps into epoch-style numbers, this is the utility for it.

How to Use:

• Paste or type one timestamp per line in the Input Timestamp box.
• Use the toggle Trim input lines to clean up spacing automatically.
• Enable Ignore invalid timestamps to skip anything that can’t be parsed cleanly.
• Use Maximize output to expand the result area if you’re working with large data.
• Click Convert to update the output manually, or let it run automatically as you type.
• Click Copy Output to copy results to clipboard (will flash “Copied!”).
• Click Export to File to save the output as a .txt file.
• Use Choose File to import a list of timestamps (supports .txt, .csv, .log, etc.)
• Click Clear All to reset everything.

What Convert Timestamp to Seconds can do:

• Converts standard datetime strings like 1970-01-01 00:00:42 into seconds since epoch (e.g., 42).
• Accepts timecodes like 01:23:45 and calculates total seconds (e.g., 5025).
• Supports natural language-friendly timestamps like July 28, 2025 12:30.
• Automatically adjusts for UTC vs local time when formatting is ambiguous.
• Skips bad entries when the Ignore invalid timestamps option is enabled.
• Helps developers debug logs, line up time-based data, or convert video timestamps.
• Fully client-side: nothing is uploaded, and no data is ever sent to a server.

Example:

Here’s a mix of time formats being converted into seconds. It includes a classic Unix timestamp, a basic HH:MM:SS timecode, an ISO 8601 UTC string, and a natural-language style datetime.

Input:

1970-01-01 00:01:00
1970-01-01T00:00:42Z
2025-07-28T12:30:00Z

Output:

60
42
1753705800

Convert Timestamp to Seconds Table:

Here’s a quick lookup for common real-world timestamps and their Unix Epoch equivalents. This is useful for log referencing, time math, and syncing systems across platforms.mp to Seconds to prep subtitle files, clean up spreadsheet logs, calculate durations in scripts, or convert time tracking data into a numerical format. It’s also handy when working with APIs or apps that require durations in raw seconds.

Common Use Cases:

This tool’s a go-to when you need to feed timestamps into APIs, databases, or log systems that run on Unix time. Whether you’re doing analytics, building time comparisons, or converting server logs, this gives you fast, accurate seconds from any readable date.
