Is that 11:59:59pm Wednesday or 11:59:59pm Thursday?
The phrase "midnight Thursday" is ambiguous and can be interpreted to mean either the beginning of the day Thursday or the end of the day Thursday. It is therefore recommended (by the National Institute of Standards and Technology) that this type of phrasing be avoided and that reference be made to 11:59 p.m. or 12:01 a.m. or by using a 24 hour clock. See http://www.nist.gov/pml/div688/times.cfm.

UA should know better.
