To all programmers here, the TZ=:<zonefile> syntax is currently unsupported in the icu library (International Components for Unicode):

https://unicode-org.atlassian.net/browse/ICU-13694

https://github.com/unicode-org/icu/pull/2213

This affects all packages that have icu as a dependency, one of them being Node.js.

https://github.com/nodejs/node/issues/37271

I discovered this the hard way when some code malfunctioned shortly after daylight savings time kicked in.

Why does the icu string library care about time zones?
