Schema

Underspecified aspect of schema: date

• Fractional seconds
  • Microsoft: 7 digits of precision
  • Apache: 3 digits of precision
  • Schema: "any number of digits"
    

• Missing timezones
  • Microsoft: local time zone
  • Apache: UTC (a.k.a. GMT)
  • Schema: unspecified can't be correlated
    

• Are timezones significant?
