My Model Class looks like this:
[DataType(DataType.Time)]
public DateTime Time {get; set;}
When I run it, I have a cool an HTML 5 Input Type in Time. When I save the data, the value in my database looks like this:
7/11/2014 1:00AM
It automatically saves the current date. I just wanna have the time saved. I'm trying to create a reservation system.

In that case you need to store that as a string. You cannot separate Time from Date using BCL (Base Class Library) of .Net. They cannot exist as independent entities.
However youcan have a workaround to save Time in a TimeSpan object using this Representing Time (not date and time) in C#

[DataType(DataType.Time)]
[DisplayFormat(ApplyFormatInEditMode = true, DataFormatString = "{0:HH:mm}")]
public DateTime Hour { get; set; }

The following will give you a string representation from your DateTime, but read the other questions and answers, and you might want to save in a format other than string to make it easier to evaluate queries...
DateTime.Now.ToString("t");

[DisplayFormat(DataFormatString = "{0:t}")]
public DateTime Time {get; set;}
will display only the time

Just change the data type as as string in database then you can save your time.
