Warning: do not attempt to implement these algorithms without proper training in temporal physics and Excel mastery.
1. The Time-Traveling Tabular Algorithm (TTTA): a method for calculating the exact moment of arrival in a parallel universe, given only a few hours' worth of coffee shop receipts.
2. The Chrono-Sync Algorithm (CSA): a complex system for syncing one's personal timeline with the timestream, utilizing a proprietary blend of VHS tapes and antique radios.
3. The Sympatico-Filter Algorithm (SFA): a tool for filtering out unwanted historical events, utilizing a neural network trained on the entirety of 90s alternative rock music.
