Definition: Day

A continuous period of 24 hours which, unless the context otherwise requires, runs from midnight to midnight.

Definition: Millisecond

The SI prefix "milli" represents a factor of 10-3, or in exponential notation, 1E-3.

So 1 millisecond = 10-3 arcseconds.

The definition of a second is as follows:

A second of arc or arcsecond is a unit of angular measurement which comprises one-sixtieth of an arcminute, or 1/3600 of a degree of arc or 1/1296000 (approximately 7.7×10-7) of a circle. It is the angular diameter of an object of 1 unit diameter at a distance of 360×60×60/(2pi) (approximately 206,265 units), such as (approximately) 1 cm at 2.1 km, or, directly from the definition, 1 astronomical unit at 1 parsec.
