Add Convert  algorithm test of time

I added the following to the test of time
· Convert a string to a number
milliseconds advanced from 00:00 When you type a letter in a valueAsNumber
· Convert a number to a string
milliseconds advanced from 00:00 If you enter a number valueAsNumber
· Convert a string to a Date
time If it is in proper format When you type a letter in a valueAsDate
· Convert a Date object to a string
Time of Date object If you set a Date object to valueAsDate

Is this the same specifications in the value property of the normal?
