set expire times

**Suppose the current time is : Sat, 11 Mar 2017 12:25:57 GMT**

**Following equivalence: 1 day after, expire**

**Support chaining sets together**

// default expire time: 1 day
    
    this.$cookies.set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX")
    
            // number + d , ignore case
    
            .set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX","1d")
    
            .set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX","1D")
    
            // Base of second
    
            .set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX",60 * 60 * 24)
    
            // input a Date, + 1day
    
            .set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX", new Date(2017, 03, 12))
    
            // input a date string, + 1day
    
            .set("user_session","25j_7Sl6xDq2Kc3ym0fmrSSk2xV2XkUkX", "Sat, 13 Mar 2017 12:25:57 GMT")

set expire times, input number type

this.$cookies.set("default_unit_second","input_value",1);            // 1 second after, expire
    this.$cookies.set("default_unit_second","input_value",60 + 30);      // 1 minute 30 second after, expire
    this.$cookies.set("default_unit_second","input_value",60 * 60 * 12); // 12 hour after, expire
    this.$cookies.set("default_unit_second","input_value",60 * 60 * 24 * 30); // 1 month after, expire

set expire times - end of browser session

this.$cookies.set("default_unit_second","input_value","0");          // end of session - use string!

set expire times , input string type
