=============== Diff against Chronology-Core-dtl.38 ===============

Item was added:
+ ----- Method: Timespan>>beCanonical (in category 'squeak protocol') -----
+ beCanonical
+ "Chronology preserves Timespans that are extracted from DateAndTime's, making Dates, Months and Years in Squeak able to represent a true Timespan of those durations starting at a specific local DateAndTime.  In case a canonical version is needed, make the receiver independent of any Timezone by removing it."
+ start makeUTC!
