Depends on the OS. There are some stoners out in Redmond who think they have developed an OS and they call it Windows. It says my UTC is -5:00 (EST). After this weekend it will still say my UTC is -5:00. They say I need to manually adjust for DST.

No, you don't have to manually adjust for DST. Windows has provided
automatic DST adjustment for many, many years and several versions
now. (I actually don't remember Windows ever NOT having this.)

What you keep doing is interpreting a *descriptive label* as somehow
referring to a *live number* suitable for calculation purposes.

The time zone is a geographic area. It doesn't change whether or not
you observe daylight time. If you live in New York throughout the
year, you are in the same time zone in July as you are in December.
Namely, you're in "Eastern Time (US & Canada)".
