Do these really differ fundamentally?
I'm assuming you can subtract 5 hours (or 4 for DST) by hand.

They're ok. There is only one NIST clock. US legal time is based
on UTC(NIST). How they actually calculate this at the ns level is
not relevant outside of the halls of NIST. Yes, most of you know
they have multiple atomic frequency standards but the product
that they disseminate is one "clock": UTC(NIST).
