I suspect this is a duplicate of #8891

hugo v0.88.0-DEV-EFEBD756+extended linux/amd64 BuildDate=2021-08-16T10:10:04-0700

Includes fix for #8891.

Confirmed with hugo v0.88.1+extended darwin/amd64 BuildDate=unknown

md	type in toml	parsed by	zone name
pass.md	String	cast	PDT
fail.md	Datetime	go-toml	""

We could regard this as an upstream issue while I guess that go-toml sets an empty timezone name intensionally.
An easy fix may be #9082 .

I'm reopening this as I tried to add the above as a test case, but it fails.

I have removed the patch that was supposed to fix this, as I didn't understand it and it came without a test case.

Note that I'm not sure this should/could be fixed:

• go-toml parses offset dates on RFC 3339 format, with empty zone name (expect for UTC, oddly enough)
• The way Hugo parses RFC 3339 is a little differently, but in my tests I get all empty zone name in this case, too. I suspect that this may be computer dependant.
