• CLDR data: http://www.unicode.org/cldr/charts/latest/supplemental/zone_tzid.html
• there are two methods (test and test2) in EsTimeZoneRule that will print out tz database info.
• to compile new time zone data on a linux machine; this was done on Fedora.
• run 'ftp ftp.iana.org'
• user is anonymous and password is your email address
• 'cd tz'
• 'get tzdata-latest.tar.gz'
• 'get tzcode-latest.tar.gz'
• 'quit' ftp
• create a temporary time zone directory, e.g., /home/donald/tz which we will call TopDir
• move both *.gz files to TopDir
• change to TopDir
• run 'tar -xzvf tzdata-latest.tar.gz'
• run 'tar -xzvf tzcode-latest.tar.gz'
• do 'chmod 666 Makefile to make it read/write.
• edit Makefile and change the line (number 40) TOPDIR= /usr/local to TOPDIR= /home/donald/tz
• save Makefile
• run 'make other_two' This will create $TopDir/etc/zoninfo-posix and $TopDir/etc/zoneinfo-leaps. The former has Dst info and the latter has Dst info and leap seconds.
• Copy both of these directories (and their sub-directories) to $VaRoot/zoneinfo.
• Add these lines to the template that creates the abt.ini file for Windows

• Time class mutateObj*. see Time test case.
• do not deprecate ANSI methods
• use Dumper → byteArrya and put contents in method.
• does windows have historical tz data?
• create an exception for bad dt and proceed wiht something.
• don't use abtError
• do explain mismatched preregs
• deprecate old dt constructors and make list
• look at subApp config expressions
• read single files.
• find system call to get tz info on linux
• make offset: do the right thing
• create GMT+1:34 on the fly
• get rid of offset as an instVar
• read versionString

• chronos download is b196. vw pulls b202 from contributed.
• Chronos uses instances of either CalendarDuration or CivilDuration to represent durations of civil time.
• An interval of time has a beginning, and end, and a duration.
• DateAndTime now return the current date and time with an offset (a Duration) of 18000 seconds or 5 hours. The offset comes from the primitive primitiveSystemOffset.
• sending asUTC to that object add the negated duration to the time and sets offset to zero. so asUTC is the same as converting to GMT.
• sending asLocal reapplies the systemOffset and sets the offset to that of the system
• timeZoneName is not implemented and throws an error

• Ubuntu may have tzName in /etc/timezone
• Fedora will have tzName in /etc/sysconfig/clock
