Nobody contributed a millisecond. Around 300 BC, the Babylonians, who worked in base 60 rather than base 10, divided the day into 60. Each unit was divided into 60, and again into 60 and so on. Conceptually, this gave them an accuracy of around 2 microseconds. "Conceptually", because they had no instruments able to measure time with anything like that precision - an hour was probably the best that they could reliably measure.
In the year 1000, al-Biruni, a Persian scholar was the first to use the term second. He divided the day into hours, 1/60 of each were minutes, 1/60 of each were seconds, 1/60 of each were thirds, 1/60 of each were fourths, The last of these was 1/3600 seconds or 0.277... recurring milliseconds.
The introduction of the decimal system brought in the prefices for thousandths (milli-) and millionths (micro-) etc, and the sequence of 60ths were abandoned.

How many minutes are there in on day?
1440 minutes. There are 60 minutes in one hour, and there are 24 hours in a day, so 60x24=1440.
What percent of a day is 3 minutes?
0.2% (approximately)
A day has 1440 minutes so 3 minutes /1440 minutes = 0.002083333 (aproximately) = 0.208% (approximately)
24 hours/day x 60 minutes/hour = 1440 minutes/day
What is 3 hour 15minute-1hour35minute equals What is 3 hour 15 minute-1hour35 minute equals?
(3hr 15min) - (1hr 35min) = (2hr 75min) - (1hr 35min) = 1hr 40min
