You put SQL in your tags, so I assume you have an SQL database with the log in and log out times in it (I know, it's a biug assumption, but be fair, you really didn't give us much to go on!)

Select min(LogInTime) , max (logOutTime) from whatevertablethedataison;

would give you what you want.

Yes they can - can you tell us what the data types are on your table and show the SQL you are using, and the error message you are getting.
