Great!! you understood for each
for the second one Now is a property of DateTime
you can keep as DateTime.Now.ToString or Now.ToString both will result same
You can check in UiPath, Place a Message Box and give like above any one and see the results
it will give Date and Time in full
But if you want to change the format of the outcome then we use (yyyy_mm_dd) or (dd_mm_yyyy) also
as your wish how to appear the date format or date time format have to
For more info check my post on conversion of format Convert Date & Time Format Tutorial
Hope this helps you
Thanks
