## Detailed Description

A class for time manipulation.

This class allows you to manipulate with time, fetch or set one. Hour can be 0 <= hour < 24. Minutes and seconds are in 0 <= val < 60.

Note
  Time where hour is 0 is always less than time where hour is 23.

Todo:
  Time is missing local/UTC option.

## Constructor & Destructor Documentation

Time | ( |  | ) |

Constructor that will set all time members to 0. This is valid time.

Time | ( | const Time & | t | ) |

Construct time via previously declared value

~Time | ( |  | ) |

Destructor

## Member Function Documentation

unsigned char hour | ( | void |  | ) | const
| inline

Returns hour

static bool is_valid | ( | unsigned char | h,
|  | unsigned char | m,
|  | unsigned char | s
| ) |  |
| static

Check if given parameters can be valid time

Returns
  true if time is valid

Parameters

  h | is hour
  m | is minutes
  s | is seconds

unsigned char minute | ( | void |  | ) | const
| inline

Returns minutes

Time& operator++ | ( |  | ) |

Increase current time by one. First seconds are increased; when they reach 59, minutes are increased and seconds are set to 0. The same applies for minutes/hour case. When hour reach for 23, it is set to 0 (the same behaviour as you see from your digital clock).

Time operator++ | ( | int |  | ) |

Suffix increment

Time& operator-- | ( |  | ) |

Reverse from operator++()

Time operator-- | ( | int |  | ) |

Suffix decrement

Time& operator= | ( | const Time & | t | ) |

Assign previously declared value. Current time will be replaced.

unsigned char second | ( | void |  | ) | const
| inline

Returns seconds

void set | ( | unsigned char | h,
|  | unsigned char | m,
|  | unsigned char | s = `0`
| ) |  |

Set time values. Values should be valid time, or assertion will be triggered.

Parameters

  h | is hour
  m | is minutes
  s | is seconds

void set_now | ( | void |  | ) |

Read system time and fill internal values

Todo:
  This should be probably a static function

bool system_set | ( | void |  | ) |

Tries to set system time with current values. This function requires priviledged user. It behaves the same as Date::system_set() (see it's documentation for detail description).

Todo:
  This should be probably a static function
