"I have the suspicion that all terrorisms (...) have little in common in their contempt for humanity. They are surpassed by certain forms of state terrorism. (...) Let's leave it at that. But I really mean what I say."

- Helmut Schmidt, Die Zeit, 30.8.2007

but even if they raise the β€œmilitary age” as in the days of the German Volkssturm, they would do well to leave me alone and not hand over weapons or ammunition - the probability is very high that I will then fire in the β€œwrong” direction

and yes, I was an excellent shot back then 🫑

## Timekeeping via Bitcoin Blocks

### Core Concept

Replace Gregorian time with **block height + intra-block offset**:

```

[Block Height]:[Seconds Since Block]

```

- **Block Height**: Sequential blockchain position (e.g., `841,234`)

- **Seconds Since Block**: Elapsed seconds since block creation (0-599)

> Example: `841234:283` = 283 seconds after Bitcoin block 841,234 was mined

# Schema

```python

def gregorian_to_btc_time(gregorian_timestamp):

genesis_block_time = 1231006505 # Bitcoin's genesis (Jan 3, 2009)

elapsed_seconds = gregorian_timestamp - genesis_block_time

block_height = elapsed_seconds // 600 # 600s = 10min block target

intra_block = elapsed_seconds % 600

return f"{block_height}:{intra_block}"

```

- **Block Clock Sync**: Nodes sync time via block headers

- **Intra-Block Precision**: Sub-minute timing handled by:

- Network propagation averages

- NTP fallback for non-critical applications

- **Epoch Anchor**: Time `0:0` = Bitcoin genesis block (2009-01-03)

Schedule transactions using **OP_CHECKLOCKTIMEVERIFY**:

```bash

# Lock payment until block 850,000 + 90s

OP_IF

OP_CHECKLOCKTIMEVERIFY 850000:90

OP_ENDIF

```

| Feature | Bitcoin Time | Gregorian |

|------------------|-----------------------|--------------------|

| **Decentralization** | Consensus-based | Government-controlled |

| **Immutability** | Cryptographically secured | Politically mutable |

| **Censorship Res** | Permissionless verification | Centralized trust |

| **Global Sync** | Blockchain-native | Timezone complexity |

### Challenges & Mitigations

1. **Block Time Variance**

- *Issue*: Actual block intervals vary (2-120 mins)

- *Solution*: Use **block height** for long-term scheduling, seconds for short-term

2. **Time Resolution**

- *Issue*: 10-minute granularity

- *Solution*: Layer-2 solutions (e.g., Lightning Network timelocks)

3. **Ecosystem Adoption**

- *Path*: Wallet integration of BTC time displays

- *Tooling*: Block explorers with dual-timestamping

- **Smart Contracts**: Trustless expiration dates

- **Document Notarization**:

```markdown

Document #XZ42F timestamped at 841234:283

[SHA-256: a1b2c3...]

```

- **Scientific Records**: Tamper-proof research logs

- **Legal Agreements**: Unforgeable effective dates

Gregorian: 2025-07-04 14:30 UTC

↓ Convert

Bitcoin Time: 841234:283 (Block 841,234 + 4m43s)

```

This system creates an apolitical, auditable time standard anchored in Bitcoin's immutable ledger – transforming time itself into a public good.

interesting, thanks for sharing

ahh, Escape from New York (1981)

one of the best films ever 🫑

it was Hitler's order to Guderian and Rommel to stop the German armored units before Dunkirk, which gave the British Expeditionary Force enough time to get to safety across the English Channel

the German generals were furious as they saw a unique opportunity to inflict a decisive defeat on the British and French

Hitler, on the other hand, wanted to enter into an alliance with Great Britain, a serious mistake that decisively changed the course of the war

and yes, it was the Red Army that won the war against Germany, not the USA
