Way over 99% of the time Bill.  But not to worry, the 2018 1120 module Federal Asset Entry Worksheet now has two data fields, one under the other, labeled 'Date acquired' and 'Date placed in service'.  Enter the date into 'Date acquired' and the 'Date placed is service' defaults to the same date automatically. PRESTO!  DONE! This feature will likely make it into the 1040 module...….never.
