| 5 | + Changes affecting future time stamps |
| 6 | + |
| 7 | + North Korea switches to +0830 on 2015-08-15. (Thanks to Steffen Thorsen.) |
| 8 | + The abbreviation remains "KST". (Thanks to Robert Elz.) |
| 9 | + |
| 10 | + Uruguay no longer observes DST. (Thanks to Steffen Thorsen |
| 11 | + and Pablo Camargo.) |
| 12 | + |
| 13 | + Changes affecting past and future time stamps |
| 14 | + |
| 15 | + Moldova starts and ends DST at 00:00 UTC, not at 01:00 UTC. |
| 16 | + (Thanks to Roman Tudos.) |
| 17 | + |
| 18 | + Changes affecting data format and code |
| 19 | + |
| 20 | + zic's '-y YEARISTYPE' option is no longer documented. The TYPE |
| 21 | + field of a Rule line should now be '-'; the old values 'even', |
| 22 | + 'odd', 'uspres', 'nonpres', 'nonuspres' were already undocumented. |
| 23 | + Although the implementation has not changed, these features do not |
| 24 | + work in the default installation, they are not used in the data, |
| 25 | + and they are now considered obsolescent. |
| 26 | + |
| 27 | + zic now checks that two rules don't take effect at the same time. |
| 28 | + (Thanks to Jon Skeet and Arthur David Olson.) Constraints on |
| 29 | + simultaneity are now documented. |
| 30 | + |
| 31 | + The two characters '%z' in a zone format now stand for the UTC |
| 32 | + offset, e.g., '-07' for seven hours behind UTC and '+0530' for |
| 33 | + five hours and thirty minutes ahead. This better supports time |
| 34 | + zone abbreviations conforming to POSIX.1-2001 and later. |
| 35 | + |
| 36 | + Changes affecting installed data files |
| 37 | + |
| 38 | + Comments for America/Halifax and America/Glace_Bay have been improved. |
| 39 | + (Thanks to Brian Inglis.) |
| 40 | + |
| 41 | + Data entries have been simplified for Atlantic/Canary, Europe/Simferopol, |
| 42 | + Europe/Sofia, and Europe/Tallinn. This yields slightly smaller |
| 43 | + installed data files for Europe/Simferopol and Europe/Tallinn. |
| 44 | + It does not affect timestamps. (Thanks to Howard Hinnant.) |
| 45 | + |
| 46 | + Changes affecting code |
| 47 | + |
| 48 | + zdump and zic no longer warn about valid time zone abbreviations |
| 49 | + like '-05'. |
| 50 | + |
| 51 | + Some Visual Studio 2013 warnings have been suppressed. |
| 52 | + (Thanks to Kees Dekker.) |
| 53 | + |
| 54 | + 'date' no longer sets the time of day and its -a, -d, -n and -t |
| 55 | + options have been removed. Long obsolescent, the implementation |
| 56 | + of these features had porting problems. Builders no longer need |
| 57 | + to configure HAVE_ADJTIME, HAVE_SETTIMEOFDAY, or HAVE_UTMPX_H. |
| 58 | + (Thanks to Kees Dekker for pointing out the problem.) |
| 59 | + |
| 60 | + Changes affecting documentation |
| 61 | + |
| 62 | + The Theory file mentions naming issues earlier, as these seem to be |
| 63 | + poorly publicized (thanks to Gilmore Davidson for reporting the problem). |
| 64 | + |
| 65 | + tz-link.htm mentions Time Zone Database Parser (thanks to Howard Hinnant). |
| 66 | + |
| 67 | + Mention that Herbert Samuel introduced the term "Summer Time". |
| 68 | + |
