Implementations

The smallest value that can be represented by PrimitiveDateTime.

Depending on large-dates feature flag, value of this constant may vary.

  1. With large-dates disabled it is equal to -9999-01-01 00:00:00.0
  2. With large-dates enabled it is equal to -999999-01-01 00:00:00.0
// Assuming `large-dates` feature is disabled.
assert_eq!(PrimitiveDateTime::MIN, datetime!(-9999-01-01 0:00));
