Detailed Description

Cache for MYSQL_TIME value with various representations.

• MYSQL_TIME representation (time) is initialized during set_XXX().
• Packed representation (time_packed) is also initialized during set_XXX().
• String representation (string_buff) is also initialized during set_XXX();
