64 位CPU理论上的数据处理能力更强。64 位 CPU 通用寄存器的位宽增加一倍,可以一次性处理 64bit 的整形数据 64 位CPU的内存寻址能力更强。32位CPU 地址总线不超过 32,它所能达到的寻址范围,理论上只能使用约 4GB,即不超过2的32次方字节;64 位 CPU,理论上寻址范围可以达到上亿 GB(2 的 64 次方字节) 当然了
Support for 64-bit TIMESTAMP data (or similar) will be part of a later release. Whether the underlying operating system uses a 64-bit time_t type is not really material. [2 Apr 2007 11:47] Valeriy Kravchuk Bug #24625was marked as a duplicate of this one. ...

On this date the Unix Time Stamp will cease to work due to a 32-bit overflow. Before this moment millions of applications will need to either adopt a new convention for time stamps or be migrated to 64-bit systems which will buy the time stamp a "bit" more time....
(I still like the idea but I don't like how much confusion it has created), instead just use a 64-bit nanosecond-precise unix timestamp. I'm not sure if this shoudl replace UUIDv7 or maybe be a separate version (we could do UUID9 ;) ). But regardless, I'm just trying to see...

For 64-bit versions of PHP, the valid range of a timestamp is effectively infinite, as 64 bits can represent approximately 293 billion years in either direction. Note: Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if...
这里的时间戳,指的就是Unix时间戳(Unix timestamp)。它也被称为Unix时间(Unix time)、 POSIX时间(POSI time),是一种时间表示方式,定义为从格林威治时间1970年01月01日00时00分00秒起至现在的总秒数。因此,严格来说,不管你处在地球上的哪个地方,哪个时区,任意时间点的时间戳都是相同的。这点有利于线上和客...
