Haitao Li	ee646eb48f	date.c: Support iso8601 timezone formats Timezone designators in the following formats are all valid according to ISO8601:2004, section 4.3.2: [+-]hh, [+-]hhmm, [+-]hh:mm but we have ignored the ones with colon so far.

Michael J Gruber	f1e9c548ce	date: avoid "X years, 12 months" in relative dates When relative dates are more than about a year ago, we start writing them as "Y years, M months". At the point where we calculate Y and M, we have the time delta specified as a number of days. We calculate these integers as: Y = days / 365 M = (days % 365 + 15) / 30 This rounds days in the latter half of a month up to the nearest month, so that day 16 is "1 month" (or day 381 is "1 year, 1 month"). We don't round the year at all, though, meaning we can end up with "1 year, 12 months", which is silly; it should just be "2 years". Implement this differently with months of size onemonth = 365/12 so that totalmonths = (long)( (days + onemonth/2)/onemonth ) years = totalmonths / 12 months = totalmonths % 12 In order to do this without floats, we write the first formula as totalmonths = (days122 + 365) / (365*2) Tests and inspiration by Jeff King.

Brandon Casey	0cc4da3036	t/t0006: specify timezone as EST5 not EST to comply with POSIX POSIX requires that both the timezone "standard" and "offset" be specified in the TZ environment variable. This causes a problem on IRIX which does not understand the timezone 'EST'. Signed-off-by: Brandon Casey <casey@nrlssc.navy.mil> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago
Jeff King	9ba0f0334d	parse_date: fix signedness in timezone calculation When no timezone is specified, we deduce the offset by subtracting the result of mktime from our calculated timestamp. However, our timestamp is stored as an unsigned integer, meaning we perform the subtraction as unsigned. For a negative offset, this means we wrap to a very high number, and our numeric timezone is in the millions of hours. You can see this bug by doing: $ TZ=EST \ GIT_AUTHOR_DATE='2010-06-01 10:00' \ git commit -a -m foo $ git cat-file -p HEAD \| grep author author Jeff King <peff@peff.net> 1275404416 +119304128 Instead, we should perform this subtraction as a time_t, the same type that mktime returns.

Jeff King	6b097788f8	t0006: test timezone parsing Previously, test-date simply ignored the parsed timezone and told show_date() to use UTC. Instead, let's print out what we actually parsed. While we're at it, let's make it easy for tests to work in a specific timezone. Signed-off-by: Jeff King <peff@peff.net> Signed-off-by: Junio C Hamano <gitster@pobox.com>	15 years ago
Johan Sageryd	dbc1b1f710	Fix '--relative-date' This fixes '--relative-date' so that it does not give '0 year, 12 months', for the interval 360 <= diff < 365. Signed-off-by: Johan Sageryd <j416@1616.se> Signed-off-by: Jeff King <peff@peff.net>	15 years ago
Jeff King	931e8e27d9	fix approxidate parsing of relative months and years These were broken by b5373e9. The problem is that the code marks the month and year with "-1" for "we don't know it yet", but the month and year code paths were not adjusted to fill in the current time before doing their calculations (whereas other units follow a different code path and are fine).

Jeff King	34dc6e73b0	tests: add date printing and parsing tests Until now, there was no coverage of relative date printing or approxidate parsing routines (mainly because we had no way of faking the "now" time for relative date calculations, which made consistent testing impossible). This new script tries to exercise the basic features of show_date and approxidate. Most of the tests are just "this obvious thing works" to prevent future regressions, with a few exceptions: - We confirm the fix in `607a9e8` that relative year/month dates in the latter half of a year round correctly. - We confirm that the improvements in b5373e9 and 1bddb25 work. - A few tests are marked to expect failure, which are regressions recently introduced by the two commits above.
