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!
