| + | * create a temporary time zone directory, e.g., / | ||
| + | * 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= / | ||
| + | * save Makefile | ||
| + | * run 'make other_two' | ||
| + | * Copy both of these directories (and their sub-directories) to $VaRoot/ | ||
| + | * 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 | ||
| + | * -------- | ||
| + | * How to write a DST primitive? | ||
| + | * What does chaining TimeZones together mean? | ||
| + | * Will DateAndTime calculations now always involve TZs? | ||
| + | * Olson versus tz? | ||
| + | * Ubuntu may have tzName in / | ||
| + | * Fedora will have tzName in / | ||
| + | * Aix has a TZ= line in / | ||
