dt(dtVal)

Causes the result of the date/time variable, constant, or calculation dtVal to be a date/time. If the output is a new variable, it will be of type date/time, but if the output variable already exists, its type is not changed.

For example, from

!newdt! = \4/25/19 08:30:00\

the type of newdt is real, but from

!newdt! = $dt(\4/25/19 08:30:00\)

the type of newdt is date/time.
