Detailed Description

The class for variables that store time zones

Backing store: Time_zone*

Note:
Time zones cannot be supported directly by my_getopt, thus these variables don't support command-line equivalents, any such command-line options should be added manually to my_long_options in mysqld.cc

set_var var 
) [inline, virtual]

save the global default value of the variable in var

Implements sys_var.

void Sys_var_tz::session_save_default ( THD *  thd,
set_var var 
) [inline, virtual]

save the session default value of the variable in var

Implements sys_var.

uchar* Sys_var_tz::session_value_ptr ( THD *  thd,
LEX_STRING *  base 
) [inline, virtual]

A pointer to a value of the variable for SHOW. It must be of show_val_type type (bool for SHOW_BOOL, int for SHOW_INT, longlong for SHOW_LONGLONG, etc).
