Add Fuzziness to Clock Times

Add a touch of randomness to your time data with the Add Fuzziness to Clock Times tool. This tool lets you slightly shift clock times forward or backward by a random number of minutes, giving your list of times a natural, human-like irregularity. It’s great for anonymizing logs, simulating real-world behavior, or just making things feel less robotic.

How to Use:

  1. Paste your list of clock times (in HH:MM format) into the input box.
  2. Adjust the Max Fuzziness slider to control how many minutes each time may shift.
  3. The tool will randomly adjust each time up or down within that range.
  4. Use Copy Output or Export to File to save your fuzzy results.
  5. Hit Clear All to reset everything.

What Add Fuzziness to Clock Times Tool can do:

This tool introduces subtle randomness to structured time data. You can apply a controlled range of minute-level variation to each time value, simulating drift, delay, or natural variance. It’s especially useful for testing time-based systems or depersonalizing time logs.

Example:

Input:

12:00
13:15
08:30
23:45

Max Fuzziness: 5 minutes

Possible Output:

11:57
13:19
08:27
23:43

Common Use Cases:

Perfect for making timestamp lists feel more natural, anonymizing personal or sensitive data, creating training/testing sets for software, or simulating how real users interact with time-based events. Helps avoid exact duplicates and improves variability.

Useful Tools & Suggestions:

Need to break things even more? Add Errors to Clock Times takes fuzziness to the next level. Or try Generate Random Time Intervals if you want a whole spread of slightly off-but-still-believable times.
