Tip checklist (authorized only)

  1. Confirm you may read the clock / format stamps on the host (lab VM / your sample / courseware).
  2. Prefer date '+%Y-%m-%d' / date -u '+%Y-%m-%dT%H:%M:%SZ' over dumping TZ databases.
  3. Record format string, UTC vs local, and any -d / -r input you actually used.
  4. Quote the stamp Evidence; never paste secrets beside it.
  5. If you need general formatting, cross-check printf-format-tips.
  6. Optional: field glue → cut-fields-tips; pattern stamps → awk-one-liners-tips.
  7. Optional: keep a copy → tee-pipe-tips; env context → env-vars-tips.
  8. Redact hostnames and sensitive labels before sharing.

Allowed framing

  • Classroom labs labeling Evidence with ISO-ish stamps you generate.
  • Binding +% format settings as Evidence.
  • Documenting "date not installed / bad format / permission denied" as valid lab outcomes.
  • Comparing date ↔ printf under one binder.

Scope we will not cover

  • No crack/pirate/keygen via date.
  • No log forgery / clock-tamper / unauthorized-access PoCs.
  • No credential-theft via timestamped secret dumps.
  • No intentional date DoS against hosts you do not own.

Beginner path (authorized only)

  1. Obtain one syllabus-approved lab VM you control.
  2. Run date -u '+%Y-%m-%dT%H:%M:%SZ' ; quote the stamp.
  3. Bind format notes as Evidence; redact sensitive labels.
  4. Optional: compare formatting with printf-format-tips.
  5. Stop at literacy — no forgery cookbooks.
Which to pick
  • Prefer authorized, short, redacted Evidence.
  • Use printf / awk / tee peers when the syllabus asks.
  • No exploit, crack, or unauthorized-access framing.

FAQ

What is a "date format tip" page in BinBench framing?

A checklist for formatting authorized timestamps on hosts you own — not a cookbook for forging logs or unauthorized clock tricks.

How does this relate to printf-format-tips?

printf-format-tips covers printf Evidence. This page zooms on date +% Evidence — it does not overwrite that page.

Can I date-format other users\' production clocks I do not administer?

No. Authorization first. BinBench will not publish unauthorized-access or clock-tamper recipes.

Does this teach exploit / log forgery via date?

No. Mentions of exploit/forgery appear only as refusals. Authorized timestamp literacy only.

Does this teach credential theft via timestamped secret dumps?

No. Redact tokens and PII before sharing formatted lines.
