Hello everyone,

Thanks a lot,

A feeder is one way. Here is another:

`  
import java.util.Date  
import java.text.SimpleDateFormat

object ISO\_TIMESTAMP {  
val isoFormat = “yyyy-MM-dd’T’HH:mm:ssZ”  
def format( d: Date ) =  
new SimpleDateFormat( isoFormat ).format( d )  
override def toString = format( new Date() )  
}

`

To use it, you would save the object into the session, like so:

`  
…exec( session =\> session.set( “CURRENT\_DATE\_TIME”, ISO\_TIMESTAMP ) )

`

Now, every time you reference ${CURRENT\_DATE\_TIME} in an expression, it will always populate with the current date/time.

If you need a date/time that doesn’t automatically update, you can do that easily enough with:

`  
…exec( session =\> session.set( “TRANSACTION\_TIMESTAMP”, ISO\_TIMESTAMP.toString ) )

`
