      Use Case

      As a BSON user
      I want Dates to decode as quickly as possible
      So that my app is more resonsive

      User Impact

      • Performance improvement for parsing Dates

      Dependencies

      • None

      Unknowns

      • The Long's construction and toNumber() calls appear redundant but do they provide value?
        • toNumber has some form of implicit truncation and precision loss
        • Note: JS Date's cannot be greater than 8640000000000000 nor less than -8640000000000000

      Acceptance Criteria

      Implementation Requirements

      • Parse Dates without creating a throw-away Long object

      Testing Requirements

      • Ensure Date's are constructed correctly and without extraneous objects

      Documentation Requirements

      • None

      Follow Up Requirements
