晋太元中,武陵人捕鱼为业。缘溪行,忘路之远近。忽逢桃花林,夹岸数百步,中无杂树,芳草鲜美,落英缤纷。渔人甚异之,复前行,欲穷其林。 林尽水源,便得一山,山有小口,仿佛若有光。便舍船,从口入。初极狭,才通人。复行数十步,豁然开朗。土地平旷,屋舍俨然,有良田、美池、桑竹之属。阡陌交通,鸡犬相闻。其中往来种作,男女衣着,悉如外人。黄发垂髫,并怡然自乐。 见渔人,乃大惊,问所从来。具答之。便要还家,设酒杀鸡作食。村中闻有此人,咸来问讯。自云先世避秦时乱,率妻子邑人来此绝境,不复出焉,遂与外人间隔。问今是何世,乃不知有汉,无论魏晋。此人一一为具言所闻,皆叹惋。余人各复延至其家,皆出酒食。停数日,辞去。此中人语云:“不足为外人道也。”(间隔 一作:隔绝) 既出,得其船,便扶向路,处处志之。及郡下,诣太守,说如此。太守即遣人随其往,寻向所志,遂迷,不复得路。 南阳刘子骥,高尚士也,闻之,欣然规往。未果,寻病终。后遂无问津者。

Structure which is used to represent datetime values inside MySQL.
We assume that values in this structure are normalized, i.e. year <= 9999,
month <= 12, day <= 31, hour <= 23, hour <= 59, hour <= 59. Many functions
in server such as my_system_gmt_sec() or make_time() family of functions
rely on this (actually now usage of make_*() family relies on a bit weaker
restriction). Also functions that produce MYSQL_TIME as result ensure this.
There is one exception to this rule though if this structure holds time
value (time_type == MYSQL_TIMESTAMP_TIME) days and hour member can hold
bigger values.
