• Work In Process -- made available for testing

• Times are moments of time: your clock and calendar
• Spans are measures in time: +(3 days), -(5 microseconds), +(1 week 2 days)

• interoperates with Date and DateTime, which are exported
• exports Base.Dates.Time as Time24, and interoperates
• interoperates with Base.Dates.Period types, which are exported

⋄ fully interoperable with DateTime, Date, Time24 types
⋄ provides a clean, easy-to-understand functional interface
⋄ enhances the ability to work with mixed time masures
⋄ covers all levels of FINRA, MiFID II timestamping

The 2018 US, EU financial regulations governing timestamps require stamped times encode UTC ±50 microseconds. This package does not know whether a conforming time server is present. The timestamps will be precise; where the time base is UTC traceable and stable, the timestamps will comply with FINRA and MiFID II 2018 regulations.

• The Year[s], Quarter[s], Month[s] forms are used with Times
• The Hour[s] .. Nanosecond[s] forms are used with Times and with Spans
• The Day and Days are synonyms, Week and Weeks are synonyms
