Combination of Date and Time Column in SQL

[jsc0624]

I was tasked to create a system from an existing system. The old system database table is shown below:

Date                                Time                              ID
5/4/2009 00:00:00           1899/12/30 07:55:30         84321

How can I query the above example to something like this?

DateTime                               ID
5/4/2009 07:55:30                 84321

I try to do this using this query:

select Date + Time as 'DateTimeRecord', ID from transdata

But unfortunately the result is this:

DateTime                               ID
5/2/2009 07:55:30                 84321
