Delphi高效定制格式的FormatDateTime

Posted 2020-11-19 marklove

本人根据歼10博主的此博文的思路进行改进,目的是高效的实现FormatDateTime(‘YYYY-MM-DD HH:NN:SS.ZZZ‘, Now);

在DelphiXE3 32Bits环境测试10,000,000次,

Delphi自带的FormatDateTime　　= 20405 ms

歼10的优化函数  = 2683 ms

本文优化函数 = 1851 ms

在DelphiXE3 64Bits环境测试10,000,000次,

Delphi自带的FormatDateTime　　= 18782 ms

歼10的优化函数  = 2091 ms

本文优化函数 = 1302ms

极限优化，进一步做了提速。
64位 XE10.1，Debug，运行10,000,000次结果：
FormatDateTime：18596 ms
歼10：2464 ms
楼顶：921 ms
本楼：795 ms

64位 XE10.1，Release，运行10,000,000次结果：
FormatDateTime：19437 ms
