Y2K38 Time Bridge - Software router for 32→64 bit epoch translation with TIBET provenance and JIS identity

tibet-y2k38

Y2K38 Time Bridge — Software router for 32→64 bit epoch translation with TIBET provenance and JIS identity.

Why replace billions of chips when a software router can catch the dumb chip?

The Problem

On January 19, 2038 at 03:14:07 UTC, the signed 32-bit Unix epoch overflows. Billions of embedded devices — PLCs, sensors, GPS receivers, ATMs, medical monitors, avionics — will wrap to negative timestamps or 1970.

You cannot replace all these chips. Many devices are:

• Embedded in walls, factories, vehicles, patients
• Safety-certified (FDA, FAA, EASA, SIL 4) — recertification takes years
• Running 20-40 year lifecycles
• Cost-prohibitive to replace at scale

The Solution

A software router that sits between legacy 32-bit devices and modern 64-bit systems:

from tibet_y2k38 import TimeBridge

# Legacy Siemens PLC with 32-bit clock
bridge = TimeBridge(
    device_id="jis:factory:plc-line4",
    clock_bits=32,
    profile="scada"
)

# Translate the maximum 32-bit timestamp
result = bridge.translate(legacy_timestamp=0x7FFFFFFF)
print(result.translated_iso)  # 2038-01-19T03:14:07+00:00

# Every translation creates a TIBET provenance token
print(result.tibet_token["erachter"])
# "32→64 bit time bridge for device jis:factory:plc-line4, profile=scada, confidence=1.00"

Every translation is:

• Identified via JIS (JTel Identity Standard) — each device has a verifiable identity
• Provenance-tracked via TIBET (Time Intent Based Event Token) — immutable audit trail
• Auditable — full chain from legacy input to 64-bit output

10 Sector Profiles

Sector	Devices Worldwide	Chip Replacement	Key Challenge
IoT	15+ billion	Impossible	Deployed in unreachable locations
SCADA	50+ million	€500-5k/unit	20+ year lifecycles, downtime = €10k-100k/hr
Automotive	1+ billion ECUs	Billions in recalls	30+ ECUs per car, 15-20 year lifespan
Medical	100+ million	Recertification = years	FDA/CE certified, patient safety critical
Telecom	10+ million	Cannot during uptime	NTP overflow hits 2036! SS7 timestamps
GPS	4+ billion	Scale impossible	Week rollover already happened (2019!)
Banking	50+ million	Mainframe = billions	COBOL packed decimal, legally binding timestamps
Energy	500+ million	Regulatory complex	Smart meters, grid frequency depends on time sync
Aviation	5+ million	FAA/EASA recert	DO-178C certification, 30-40 year aircraft life
Rail	10+ million	SIL 4 safety critical	ERTMS/ETCS, incorrect time = collision risk

from tibet_y2k38 import TimeRouter

router = TimeRouter(network_id="jis:factory:eindhoven")

# Each device gets its sector-specific configuration
router.add_device("jis:plc:line4", profile="scada")      # BCD datetime
router.add_device("jis:gps:antenna", profile="gps")       # GPS week number
router.add_device("jis:atm:lobby", profile="banking")     # COBOL packed
router.add_device("jis:ntp:server1", profile="telecom")   # NTP 32-bit

# Route timestamps through the correct bridge
result = router.translate("jis:plc:line4", timestamp=0x7FFFFFFF)

Compliance

Built-in compliance reporting for:

• NIS2 (EU Directive 2022/2555) — Asset inventory, risk assessment, incident reporting, audit trails
• ISO/IEC 5338 (AI system lifecycle) — Data lineage, provenance tracking, lifecycle documentation

from tibet_y2k38.compliance import NIS2Reporter, ISO5338Reporter

nis2 = NIS2Reporter(router)
print(nis2.risk_assessment())   # Devices at risk, mitigation status
print(nis2.audit_trail_report()) # TIBET provenance proof

iso = ISO5338Reporter(router)
print(iso.data_lineage_report()) # Full translation pipeline lineage
