type TDateTime = type Double;
function Now: TDateTime;
Returns the current system date and time.
The integral part of a TDateTime value is the number of days that have passed since 12/30/1899. The fractional part of a TDateTime value is fraction of a 24 hour day that has elapsed.
To find the fractional number of days between two dates, simply subtract the two values. Likewise, to increment a date and time value by a certain fractional number of days, simply add the fractional number to the date and time value.
