Parsing time stamps faster with SIMD instructions – Daniel Lemire's blog

In software, it is common to represent time as a time-stamp string. It is usually specified by a time format string. Some standards use the format %Y%m%d%H%M%S meaning that we print the year, the month, the day, the hours, the minutes and the seconds. The current time as I write this blog post would be 20230701205436 as a time stamp in this format. It is convenient because it is short, easy to rea

タイムスタンプを示す文字列のパースはSIMDで既存実装(strptime)よりも6倍高速に。日時のパースなんて日常茶飯事なのでこれは良いね。
