mattc-catalyst	f476ae28eb	MDL-11538: lib/olson - bugfix, olson time-zone import doesn't deal with rule changes in the future ... Author: Matt Clarkson <mattc@catalyst.net.nz>	2007-10-02 01:43:07 +00:00
stronk7	c0fe3453ef	Change rule to tzrule (reserved word)	2006-08-22 20:10:54 +00:00
martinlanghoff	3f8701ba14	Fixed handling of zones with no pre 1970 entries. Strange bug identified and fixed by Jon.	2005-05-22 09:15:52 +00:00
martinlanghoff	6227e876f6	olson_simple_rule_parser() now adds a reset rule to rulesets where the last rule has a defined TO field that marks where it ends. This tonge-twister means that Asia/Seoul should see the 1987 DST rule deactivated correctly in modern times. Discussed in http://moodle.org/mod/forum/discuss.php?d=23957	2005-05-18 07:53:45 +00:00
martinlanghoff	47121b3865	Now comments don't break Zone continuation, should fix reported issues with the Europe/Paris zone definition.	2005-05-02 10:26:26 +00:00
moodler	a1e93da26c	Improvements to timezone import interface	2005-04-10 09:31:58 +00:00
martinlanghoff	798065253e	Two minor fixes to Olson file parsing. olson_parse_at() now deals correctly with 'unsigned' AT entries. olson_simple_rule_parser() avoid a potential bug in minute-only SAVE entries.	2005-04-02 06:28:02 +00:00
defacer	733191ab83	Fixes fixes fixes fixes.	2005-03-23 04:00:46 +00:00
defacer	d37317b249	"from" is a reserved word in SQL, so change the field to "year"	2005-03-23 03:02:45 +00:00
defacer	62a73d8949	Continuing to move towards the "pre-calculated array in $SESSION" approach, ... we output just ONE record for each year that something changes. This knocks another ~3000 records from mdl_timezone.	2005-03-23 02:10:45 +00:00
defacer	aedcf71e33	Treat 'max' as 'only' in the "until" field. This removes ~1500 useless records.	2005-03-23 01:57:15 +00:00
defacer	deab60a42b	My latest working version, but we 'll need to roll back a bit as there ... are more changes planned (from_timestamp bites the dust etc).	2005-03-23 01:24:22 +00:00
defacer	621d6c9c2b	Fixing a logic error... awgod.	2005-03-18 04:26:50 +00:00
defacer	7df4ed34be	Continuing to debug... we now have a SINGLE rule with from_timestamp = 0, guaranteed.	2005-03-18 04:02:59 +00:00
defacer	e0a3a2921a	Improvements and robustness, it now appears to be parsing a concatenation ... of all relevant Olson files successfully.	2005-03-18 03:06:46 +00:00
defacer	4fe76cc138	Typo.	2005-03-16 03:46:17 +00:00
defacer	01b4c10789	olson_parse_on() now parses as agreed for the new timezone settings.	2005-03-16 03:41:56 +00:00
defacer	5e4e027fea	Pre-emptively put a lower bound of 1970 to years, instead of putting a lower ... bound of 0 to the generated timestamps. Windows' < 1970 bug won't have it otherwise.	2005-03-12 01:20:37 +00:00
martinlanghoff	eb4e67a27f	The olson parser is feature complete and ready for people to start playing with it. The entry point is the olson_todst($filename) function.	2005-03-07 07:39:27 +00:00
martinlanghoff	b87a5a23a5	Reorganized the rules and fixed a couple of bugs in the olson zone parser	2005-03-05 02:43:07 +00:00
martinlanghoff	af2309e366	We now postpone parsing of AT until we have the GMTOFFSET handy; some reorganization of the returned arrays, and starting to prepare the rationalized DST entries for Moodle DST table	2005-03-04 12:05:26 +00:00
martinlanghoff	720e6293ad	Olson parser now parses Zones and Rules	2005-03-04 10:59:29 +00:00
defacer	6ebb179eb2	"Reasonable assumptions" if a set or reset time is missing for some year.	2005-02-25 18:44:41 +00:00
defacer	83e1fc1407	Trying to get the Olson parser to produce correct output. That format is a nightmare...	2005-02-25 18:28:12 +00:00
martinlanghoff	8b0660a3c5	Initial implementation of a simple Olson database file format for DST rule parsing. Implements olson_simple_rule_parser().	2005-02-23 06:45:45 +00:00
