Are global and thread_local the same?

[memark]

Reading in the docs:

mock_instant::global

• MockClock will have a new state per thread
• Instantwill have a new state per thread
• SystemTime will have a new state per thread

mock_instant::thread_local

• MockClock will have a new state per thread
• Instantwill have a new state per thread
• SystemTime will have a new state per thread

all of them say "new state per thread", which I didn't expect. Is this a typo? If not, what difference is this section trying to describe?

It is a typo, global uses a mutex to keep the same state across all threads (e.g. unit tests)
