Precisely.

That won't work :)

��

'1/1/1990' asDate =��

(DateAndTime fromString: '1990-01-01T00:00:00Z') asDate ->�� true

(DateAndTime fromString: '1990-01-01T00:00:00Z') asDate start ->�� 1990-01-01T00:00:00-04:00

The date doesn't change converted to local timezone.�� So you could solve your problem by comparing just the date part��yyyymmdd.��

Note that��

Timespan >> = comparand

^ self class = comparand class��

and: [ self start = comparand start

and: [ self duration = comparand duration ] ]

Maybe a good solution is to modify the start check for the Date class?�� I don't seem to have any real control over the start so having that be part of my check and fail seems wrong on this class.

Date >> starting: aDateAndTime

^super starting: (aDateAndTime midnight) duration: (Duration days: 1)

Suggest the fix is��

Date>> = comparand

^ self class = comparand class��

and: [ "Converts to current tz for comparision"

�� self start midnight = comparand start midnight��

and: [ self duration = comparand duration ] ]

Date>> = comparand

^ self class = comparand class��

and: [ "Compare only date part"��

�� self start yyyymmdd = comparand start yyyymmdd

and: [ self duration = comparand duration ] ]

Seems to match the intent of the class without changing the timezone.

All the best,

I guess it would make sense for consistency and thinking further,
`yesterday` and friends suffer from the same problems we've been discussing.
