Today (Saturday) We will make some minor tuning adjustments to MySQL.

You may experience 2 up to 10 seconds "glitch time" when we restart MySQL. We expect to make these adjustments around 1AM Eastern Daylight Saving Time (EDT) US.

zdump - time zone dumper
zdump [--version] [-v] [-c [loyear,]hiyear] [zonename]...
The zdump command prints the current time for each time zone (zonename) listed on the command line. Specify zonename as the name of the time zone database file relative to /usr/share/lib/zoneinfo. Specifying an invalid time zone (zonename) to zdump does not return an error, rather zdump uses GMTO. This is consistent with the behavior of the library calls; zdump reflects the same behavior of the time routines in libc. See ctime(3C) and mktime(3C).
The following options are supported: --version Outputs version information and exits. -v Displays the entire contents of the time zone database file for zonename. Prints the time at the lowest possible time value; the time one day after the lowest possible time value; the times both one second before and exactly at each time at which the rules for computing local time change; the time at the highest possible time value; and the time at one day less than the highest possible time value. See mktime(3C) and ctime(3C) for information regarding time value (time_t). Each line of output ends with isdst=1 if the given time is Daylight Saving Time, or isdst=0 otherwise. -c [loyear],hiyear Cuts off the verbose output near the start of the given year(s) . By default, the program cuts off verbose output near the start of the years -500 and 2500.
The following exit values are returned: 0 Successful completion. 1 An error occurred.
/usr/share/lib/zoneinfo Standard zone information directory
