Provide a dateTimeNow expression?

[jitenderaswani]

I am taking a long route to get dateTimeNow expression
val dt = DateTime.now()
val fmt = DateTimeFormat.forPattern("yyyy-MM-dd HH:mm:ss")
val endDate = fmt.print(dt)
val period = dateTime(endDate) - 30.day to dateTime(endDate)

Would be awesome to compress this to:
val period = dateTimeNow() - 30.day to dateTimeNow()
