Gem to efficiently manipulate the time, adding, subtracting and converting hours.

## Installation

Add this line to your application's Gemfile:

```ruby
gem 'tempus'
```

And then execute:

    $ bundle

Or install it yourself as:

    $ gem install tempus

## Usage
 With this gem you can manage durations of time.

### Initialize with duration
```ruby
  hours = Tempus.new(30.hours  + 5.minutes + 3.seconds)
  => <Tempus:8508680 seconds=108303.0, formated=30:05:03>
  hours.value_in_minutes
  => 1805.05
  hours.to_s("%H hours and %M minutes")
  => "30 hours and 05 minutes"
```
### Convert from other types
```ruby
  hours = "35:05:01".to_tempus
  => <Tempus:7228060 seconds=126301.0, formated=35:05:01>
  hours + 6.hours
  => <Tempus:6931320 seconds=147901.0, formated=41:05:01>
```
```ruby
  Tempus.new(Time.now)
  => <Tempus:6578680 seconds=46455.162950918, formated=12:54:15>
```

### Sum durations

```ruby
  "1:00:00".to_tempus + "2:00"
  => <Tempus:6634700 seconds=10800.0, formated=03:00:00>
```
