That would be:
DATEPARSE('yyyyMMddHHmmss', [Date String])
For time elapsed, you can use the DATEDIFF syntax:
DATEDIFF('second', [Date 1], [Date 2])
Thank you very very very much for your quick and excellent response!!!! It works!!! You ROCK!!!
There are many great gurus here in the Community, but I've come to accept Pooja's responses as golden. :-)
Omg! Thank you both for the kind words I am still learning myself, but the appreciation is very humbling and encouraging. Thank you much!
