This commit removes all usages of github.com/jinzhu/now.

github.com/jinzhu/now has numerous errors handling date and time. The example's of them are:
1. Incorrect handling of DST (https://github.com/jinzhu/now/issues/13).
2. 24 Hour long days (https://stackoverflow.com/questions/25254443/return-local-beginning-of-day-time-object-in-go) Chicago has 23, 24, or 25 hours in a day.
3. Incorrect usage of time.Truncate which can return time with a non-zero minute, depending on the time's Location. (https://github.com/golang/go/issues/16647).

There are other issues as well, including getting incorrect beginning and end of the month.

-## Now
-
-Now is a time toolkit for golang
-
-#### Why the project named `Now`?
-
-```go
-now.BeginningOfDay()
-```
-`now` is quite readable, aha?
-
-#### But `now` is so common I can't search the project with my favorite search engine
-
-* Star it in github [https://github.com/jinzhu/now](https://github.com/jinzhu/now)
-* Search it with [http://godoc.org](http://godoc.org)
-
-## Install
-
-```
-go get -u github.com/jinzhu/now
-```
-
-### Usage
-
-```go
-import "github.com/jinzhu/now"
-
-time.Now() // 2013-11-18 17:51:49.123456789 Mon
-
-now.BeginningOfMinute()   // 2013-11-18 17:51:00 Mon
-now.BeginningOfHour()     // 2013-11-18 17:00:00 Mon

-now.BeginningOfWeek()     // 2013-11-17 00:00:00 Sun
-now.FirstDayMonday = true // Set Monday as first day, default is Sunday
-now.BeginningOfWeek()     // 2013-11-18 00:00:00 Mon
-now.BeginningOfMonth()    // 2013-11-01 00:00:00 Fri
-now.BeginningOfQuarter()  // 2013-10-01 00:00:00 Tue
-now.BeginningOfYear()     // 2013-01-01 00:00:00 Tue

-now.EndOfMonth()          // 2013-11-30 23:59:59.999999999 Sat
-now.EndOfQuarter()        // 2013-12-31 23:59:59.999999999 Tue
-now.EndOfYear()           // 2013-12-31 23:59:59.999999999 Tue
-
-
-// Use another time
-t := time.Date(2013, 02, 18, 17, 51, 49, 123456789, time.Now().Location())
-now.New(t).EndOfMonth()   // 2013-02-28 23:59:59.999999999 Thu
-
-
-// Don't want be bothered with the First Day setting, Use Monday, Sunday
-now.Monday()              // 2013-11-18 00:00:00 Mon
-now.Sunday()              // 2013-11-24 00:00:00 Sun (Next Sunday)
-now.EndOfSunday()         // 2013-11-24 23:59:59.999999999 Sun (End of next Sunday)
-
-t := time.Date(2013, 11, 24, 17, 51, 49, 123456789, time.Now().Location()) // 2013-11-24 17:51:49.123456789 Sun
-now.New(t).Monday()       // 2013-11-18 00:00:00 Sun (Last Monday if today is Sunday)
-now.New(t).Sunday()       // 2013-11-24 00:00:00 Sun (Beginning Of Today if today is Sunday)
-now.New(t).EndOfSunday()  // 2013-11-24 23:59:59.999999999 Sun (End of Today if today is Sunday)
-```
-
-#### Parse String
-
-```go
-time.Now() // 2013-11-18 17:51:49.123456789 Mon
-
-// Parse(string) (time.Time, error)
-t, err := now.Parse("12:20")            // 2013-11-18 12:20:00, nil
-t, err := now.Parse("1999-12-12 12:20") // 1999-12-12 12:20:00, nil
-t, err := now.Parse("99:99")            // 2013-11-18 12:20:00, Can't parse string as time: 99:99
-
-// MustParse(string) time.Time
-now.MustParse("2013-01-13")             // 2013-01-13 00:00:00
-now.MustParse("02-17")                  // 2013-02-17 00:00:00
-now.MustParse("2-17")                   // 2013-02-17 00:00:00
-now.MustParse("8")                      // 2013-11-18 08:00:00
-now.MustParse("2002-10-12 22:14")       // 2002-10-12 22:14:00
-now.MustParse("99:99")                  // panic: Can't parse string as time: 99:99
-```
-
-Extend `now` to support more formats is quite easy, just update `TimeFormats` variable with `time.Format` like time layout
-
-```go
-now.TimeFormats = append(now.TimeFormats, "02 Jan 2006 15:04")
-```
-
-Please send me pull requests if you want a format to be supported officially
