The number of days between datetimes.
The number of days between two datetimes
|FromDateTime||A starting datetime in OI internal format. (REQUIRED)|
|ToDateTime||An ending datetime in OI internal format. (REQUIRED)|
|Fractional||Determines if the span should be in whole days or fractional days. (OPTIONAL)|
The "DaySpan" service calculates the number of days between two datetimes. The result will be positive if the starting datetime comes before the ending datetime and negative if the ending datetime comes first.
If Fractional is set to 1, which is the default, you will get a decimal number if the time of day is not the same for each datetime. If you want whole days only, set Fractional to 0.
