[dba-SQLServer] Update using GetDate()

If I update a field in millions of records with GetDate, will every record get the same date / time 
value?  Or will later updates get a later time if the time of that record update happens a second or 
more later than earlier updates?


IOW does SQL Server get one date/time value and use that value for all updates in that query?
