Help Request: DateTime Math Possible?

[mhsimkin]

Is it possible to do math on DateTime objects?

Given the following:
Start: DateTime
End: DateTime

I'm looking to do the following operations:
{{Start-1}}
{{End-Start}}

Is this possible?

Thanks

No, that's not possible. The expression (or Selector as we call it) is supposed to remain simple, and does not support any logic. It just supports getting properties, or can call a parameterless method (such as ToString or ToUpper, but that's it.
Mostl other logic should be handled by code. For example:

Smart.Format("{Start} {End} ({Duration})", new { Start, End, Duration = End-Start });
