Timekeeping in 700 BC vs. Modern Quebec Time Zones

The premise contains an anachronism: standardized time zones and the 24-hour clock did not exist in 700 BC.

Ancient Timekeeping (c. 700 BC)

• Based on solar observation (sundials, shadow clocks, water clocks clepsydra).
• Hours varied by season (temporal hours: 1/12 of daylight/darkness).
• Local noon = sun's highest point. No coordination between cities.
• Civilizations: Babylonians, Egyptians, Greeks, Zhou China, pre-Columbian Americas each had own systems.

Modern Quebec Time

• Eastern Standard Time (EST): UTC-5 (Nov–Mar)
• Eastern Daylight Time (EDT): UTC-4 (Mar–Nov)
• Based on atomic clocks, global coordination (UTC), legal statutes.

Answering the Question

There is no meaningful conversion between a hypothetical "700 BC time" and modern Quebec time. They are incommensurable systems. If you are writing fiction or a game, you would invent a plausible ancient time notation (e.g., "3rd hour of the night watch") and note the modern equivalent for readers.
