On my machine I have a service to synchronise the SYSTEM time (including Time zone), and would like the DB will synchronize with the machine time once in a while.
When I change SYSTEM time, MySQL keep giving the old time when I use
CURRENT_TIMESTAMP, It synchronize it only when I restart the MySQL service.
I would like to ask: is it possible, by update some system variable, or anything else, to set the DB time, to be equal to the SYSTEM time, or any other time, without a restart of the service?
I don't want to stop the DB at all. I think that maybe a sceduled task, which run once in a while, can be set, but what should it do?
To accept answer, it must pass the following test:
# change system time, date or timezone on the machine select CURRENT_TIMESTAMP from dual; #--still show old time call sync_time; #or some sync date + time + timezone commands... select CURRENT_TIMESTAMP from dual; #--will show updated time
I just need the sync_time procedure, that will cause the last select to show the machine date and local time.
@rathishDBA answer didn't helped at all, it only changed the MySQL variables, not sync the DB time. I tried it as the 'root' user and both first and last select gave me the same unsynced result.
System time = 2:07 CURRENT_TIMESTAMP = 11:37
