News for the tz database
+Release 2025a - 2025-01-15 10:47:24 -0800
+
+ Briefly:
+ Paraguay adopts permanent -03 starting spring 2024.
+ Improve pre-1991 data for the Philippines.
+ Etc/Unknown is now reserved.
+
+ Changes to future timestamps
+
+ Paraguay will stop changing its clocks after the spring-forward
+ transition on 2024-10-06, so it is now permanently at -03.
+ (Thanks to Heitor David Pinto and Even Scharning.)
+ This affects timestamps starting 2025-03-22, as well as the
+ obsolescent tm_isdst flags starting 2024-10-15.
+
+ Changes to past timestamps
+
+ Correct timestamps for the Philippines before 1900, and from 1937
+ through 1990. (Thanks to P Chan for the heads-up and citations.)
+ This includes adjusting local mean time before 1899; fixing
+ transitions in September 1899, January 1937, and June 1954; adding
+ transitions in December 1941, November 1945, March and September
+ 1977, and May and July 1990; and removing incorrect transitions in
+ March and September 1978.
+
+ Changes to data
+
+ Add zone1970.tab lines for the Concordia and Eyre Bird Observatory
+ research stations. (Thanks to Derick Rethans and Jule Dabars.)
+
+ Changes to code
+
+ strftime %s now generates the correct numeric string even when the
+ represented number does not fit into time_t. This is better than
+ generating the numeric equivalent of (time_t) -1, as strftime did
+ in TZDB releases 96a (when %s was introduced) through 2020a and in
+ releases 2022b through 2024b. It is also better than failing and
+ returning 0, as strftime did in releases 2020b through 2022a.
+
+ strftime now outputs an invalid conversion specifier as-is,
+ instead of eliding the leading '%', which confused debugging.
+
+ An invalid TZ now generates the time zone abbreviation "-00", not
+ "UTC", to help the user see that an error has occurred. (Thanks
+ to Arthur David Olson for suggesting a "wrong result".)
+
+ mktime and timeoff no longer incorrectly fail merely because a
+ struct tm component near INT_MIN or INT_MAX overflows when a
+ lower-order component carries into it.
+
+ TZNAME_MAXIMUM, the maximum number of bytes in a proleptic TZ
+ string's time zone abbreviation, now defaults to 254 not 255.
+ This helps reduce the size of internal state from 25480 to 21384
+ on common platforms. This change should not be a problem, as
+ nobody uses such long "abbreviations" and the longstanding tzcode
+ maximum was 16 until release 2023a. For those who prefer no
+ arbitrary limits, you can now specify TZNAME_MAXIMUM values up to
+ PTRDIFF_MAX, a limit forced by C anyway; formerly tzcode silently
+ misbehaved unless TZNAME_MAXIMUM was less than INT_MAX.
+
+ tzset and related functions no longer leak a file descriptor if
+ another thread forks or execs at about the same time and if the
+ platform has O_CLOFORK and O_CLOEXEC respectively. Also, the
+ functions no longer let a TZif file become a controlling terminal.
+
+ 'zdump -' now reads TZif data from /dev/stdin.
+ (From a question by Arthur David Olson.)
+
+ Changes to documentation
+
+ The name Etc/Unknown is now reserved: it will not be used by TZDB.
+ This is for compatibility with CLDR, which uses the string
+ "Etc/Unknown" for an unknown or invalid timezone. (Thanks to
+ Justin Grant, Mark Davis, and Guy Harris.)
+
+ Cite Internet RFC 9636, which obsoletes RFC 8536 for TZif format.
