Case 04 — Proof of time

Timestamped screenshot of a website

A timestamp only means something when someone other than you recorded it. Paste a URL below and SnapMySite's servers capture the full page, stamp the exact UTC time, fingerprint the file with SHA-256, and email it to you — so you can show not just what a page said, but when it said it.

UTC timestamp · SHA-256 hash · emailed record · $1 gets 5 captures

Three timestamps, none of them yours

Each capture is dated three independent ways:

  1. The capture record — our server logs the exact UTC moment the page was rendered.
  2. The email — delivery through mail infrastructure adds its own headers and dates, created by systems neither party controls.
  3. The hosted link — the stored file carries its capture time and stays available for verification for the whole retention period.

That's the difference between "trust me, I took this on Tuesday" and a paper trail.

The hash makes it tamper-evident

Every file gets a SHA-256 hash — a 64-character fingerprint computed from its exact contents. Anyone can recompute the hash of your copy with free tools and compare. Match: the file is untouched since capture. Mismatch: it isn't. There's no arguing with arithmetic.
