Problem with time_zone system variable

[Shaukat Mahmood Ahmad]

Hi All,

Within my custom storage engine, I want to get time zone of client
machine from where I received current query, I am using following code
but it does not return any thing.


THD* thd = this->ha_thd();
system_variables sys_vars = thd->variables;

bool time_zone_used = thd->time_zone_used;

Time_zone* timezone = sys_vars.time_zone;
const char* name = timezone->get_name()->ptr(); // Unhandled exception


Can anyone help me how can I get system (MySQL server machine) and
session (mysql client machine) time zone information?


Regards,
SMA
