Nearly all major date/time libraries compute hour, minute and second the same way - slowly . In this article, I will dive deep into this little problem, and demonstrate a seemingly impossible claim:
A daily timestamp [0..86399] can be converted into Hour, Minute and Second – with the latency of only two multiplications (and on some targets even lower!) .
This is in contrast to most date libraries which take around 16 cpu-cycles to compute.
