These "strange dates" are a product of Excel's display, not 
EnergyPlus.  The values of the daylighting -- you can look at the raw 
csv file and see that the Mon/Day is, for example, 1/13 though your 
excel file now says that is 1/1/2013.

Your location object
Location,
     11-7,                    !- LocationName
     30.13,                   !- Latitude {deg}
     31.4,                    !- Longitude {deg}
     2,                       !- TimeZone {hr}
     74;                      !- Elevation {m}

has set the time zone as +2, but the weather file has the time zone 
set at 1.  If a weather file is attached, it automatically overrides 
the value of the Location object in the IDF.

The warning in the .err file:
    ** Warning ** Weather file location will be used rather than 
entered Location object.
    **   ~~~   ** ..Location object=11-7
    **   ~~~   ** ..Weather File Location=CAIRO INTL AIRPORT AL 
QAHIRAH EGY ETMY WMO#=623660

tells you that but does not describe all the possible implications.
