To obtain metadata about events:
Event Scheduler Time Representation
Each session in MySQL has a session time zone (STZ). This is the
time_zone value that is
initialized from the server's global
time_zone value when the session
begins but may be changed during the session.
The session time zone that is current when a
CREATE EVENT or
ALTER EVENT statement executes is
used to interpret times specified in the event definition. This
becomes the event time zone (ETZ); that is, the time zone that is
used for event scheduling and is in effect within the event as it
For representation of event information in the data dictionary,
ends times are converted to UTC and stored
along with the event time zone. This enables event execution to
proceed as defined regardless of any subsequent changes to the
server time zone or daylight saving time effects. The
last_executed time is also stored in UTC.
Event times can be obtained by selecting from the
INFORMATION_SCHEMA.EVENTS table or
SHOW EVENTS, but they are
reported as ETZ or STZ values. The following table summarizes
representation of event times.
