## Detailed Description

C++ form of SQL's TIME type.

Objects of this class can be inserted into streams, and initialized from SQL TIME strings.

## Constructor & Destructor Documentation

## ◆ Time() [1/4]

mysqlpp::Time::Time | ( | unsigned char | h,
|  | unsigned char | m,
|  | unsigned char | s
| ) |  |
| inline

Initialize object.

Parameters

  h | hour, 0-255 (yes, > 1 day is legal in SQL!)
  m | minute, 0-59
  s | second, 0-59

## ◆ Time() [2/4]

mysqlpp::Time::Time | ( | const char * | str | ) |
| inlineexplicit

Initialize object from a C string containing a SQL time string.

String must be in the HH:MM:SS format. It doesn't have to be zero-padded.

## ◆ Time() [3/4]

template<class Str >

mysqlpp::Time::Time | ( | const Str & | str | ) |
| inlineexplicit

Initialize object from a C++ string containing a SQL time string.

This works with any stringish class that declares a c_str() member function: std::string, mysqlpp::String...

See also
  Time(const char*)

## ◆ Time() [4/4]

mysqlpp::Time::Time | ( | time_t | t | ) |
| explicit

Initialize object from a `time_t`.

Naturally, we throw away the "date" part of the `time_t`. If you need to keep it, you want to use DateTime instead.

## Member Function Documentation

## ◆ compare()

int mysqlpp::Time::compare | ( | const Time & | other | ) | const
| virtual

Compare this time to another.

Returns < 0 if this time is before the other, 0 of they are equal, and > 0 if this time is after the other.

Implements mysqlpp::Comparable< Time >.

## ◆ operator time_t()

mysqlpp::Time::operator time_t | ( |  | ) | const

Convert to time_t.

The "date" part of the `time_t` is "today"
