Which data type stores date/time as seconds since midnight on 12/31/1840?

• A. Chronicles Data Type - Instant
• B. Chronicles Data Type - Time
• C. Chronicles Data Type - String
• D. Chronicles Data Type - Number

Answer: (A)

An instant represents a precise moment in time expressed as the number of seconds from a fixed starting point. In this model, date/time values are stored as seconds since midnight on 12/31/1840, so the stored value directly encodes that moment relative to that epoch. This makes it the right choice for timestamps because it preserves exact order and allows precise calculations across dates and times. A Time type would cover only a time of day without a date, so it can’t represent a full date/time. A String would keep a human-readable representation rather than a numeric timestamp, and a Number would be just a raw value without the explicit meaning of a timestamp. Therefore, Chronicles Data Type - Instant is the correct fit.
