RE: Daylight Saving Time -- MIDRANGE-L

Even if you check with external, the time shift occurs automatically
with QN0500EST or EST2 (or any other zone if enabled), as indicated if
you click Edit... With your time zone selected, then click the Daylight
Saving Time tab.  Ensure "Enable Daylight Saving Time" is checked,
ensure the dates below are correct, and everything will work magically.

Always good to check on the systems those nights, though.  The automated
checker (SNTP client) will be **WAY** off, but since the system will
know a time adjustment is in-progress, it shouldn't even check anyway.
Then once you're done with the DST on/DST off, it'll continue to
reference the time source, and since your UTC offset changed, all should
be well on the next check.

back to the subject at hand,  I'm wondering about how this is done as
well.  I'm not responsible for making this shift anywhere, but I have
clients who are probably not even thinking about this.

I can swoop in and be the hero!
