[ANN] TZ-Olson on SqueakMap
by David T. Lewis 12 Mar '19

12 Mar '19

TZ-Olson is an Olson time zone database for Squeak. It is now listed on SqueakMap at http://map.squeak.org and maintained at http://www.squeaksource.com/TimeZoneDatabase. See https://en.wikipedia.org/wiki/Tz_database for background and general information. The class comment for TimeZoneDatabase provides additional details. The Squeak Chronology package, especially class DateAndTime, represents time in terms of magnitude (seconds relative to a Posix or Smalltalk reference point) and offset from UTC, where the offset allows the DateAndTime to be displayed relative to a local timezone. When combined with Olson time zone tables, any instance of DateAndTime may be displayed for another time zone, and a local time specification in any time zone may be used to create a DateAndTime instance with correct magnitude. TZ-Olson is a subset of the original TimeZoneDatabase package for Squeak, and replaces it for Squeak images beginning with Squeak 5.3. Examples: To show the current time in central Europe: DateAndTime now inTimeZoneNamed: 'CET' To create a DateAndTime for a local time in another time zone, accounting for daylight savings time changes: DateAndTime year: 2013 month: 3 day: 31 hour: 13 minute: 17 second: 19 inTimeZoneNamed: 'CET' To locate a suitable time zone: TimeZoneDatabase grepFor: 'CET'. TimeZoneDatabase grepFor: 'Detroit'. To set the default time zone in the database to match that of your operating system: TimeZoneDatabase defaultLocation: 'CET'. To inspect daylight savings transition times: TimeZoneDatabase defaultTimeZone dstTransitionTimes. Dave

Testing out new UTCDateAndTime in Squeak 5.3 alpha
by Tim Johnson 11 Mar '19

11 Mar '19

Hi all, I am testing out UTCDateAndTime via trunk. I am happy with the results so far, and intend to send along some notes in the near future. One of my tests was refusing to pass, though, and I have narrowed it down to this new behavior which I find kind of strange. | d span | d := DateAndTime now. span := (DateAndTime now - 5 minutes) to: DateAndTime now. span includes: d. " false" d := DateAndTime now. span := (DateAndTime now - 5 minutes) to: (DateAndTime now + 1 milliSecond). span includes: d. " true" d := DateAndTime now - 1 milliSecond. span := (DateAndTime now - 5 minutes) to: (DateAndTime now). span includes: d. " true" What am I doing wrong? I am running on OS X using Cog Spur VM 5.0-201803080952 (64-bit). Thanks, Tim J

OSProcess for Pharo 7
by Max Leske 11 Mar '19

11 Mar '19

Hi all, Pharo 7 no longer includes #ifNotNilDo:, meaning that OSProcess loading fails. I volunteer to update OSProcess for Pharo 7 but I need someone to tell me what the expected workflow is. AFAICT, we've simply copied the current ConfigurationOf to the MetaRepoForXX in the past without making any changes specific to Pharo. That will not work this time. So, should I create a new version of OSProcess for all platforms, where #ifNotNilDo: has been replaced with #ifNotNil:? Or should I add a compatibility package for Pharo? Or something else? Cheers, Max
