unix/epoch time that also took timezone into account. So I decided to share what I came up with. Basically it takes the timestamp in UTC time and then provides the epoch time also in UTC time. Any downstream system then can convert to date time and adjust to their preferred time zone...
从Oracle9i开始提供的INTERVAL类型,它支持存储时间差(如“两年零五个月”或“三天零十八个小时零四十五分钟”),并可以与DATE或TIMESTAMP进行加法运算以生成一个新的DATE/TIMESTAMP值。 本文主要介绍DATE类型,但适用于DATE的大部分功能也适用于TIMESTAMP。 (有关TIMESTAMP和INTERVAL类型的更多背景知识,请阅读 Jonathan Ge...
