The majority of time data is not even floating point and for most use cases floats don't make sense there (you usually have a set precision you want to have and don't have varying orders of magnitude)

Almost all operating systems and programming languages use metric fractions of the second for time (https://en.wikipedia.org/wiki/System_time#Retrieving_system_...) the only common technology that I know that doesn't is NTP.
