are the relatives 'when' and 'that' interchangeable when following the antecedent involving the meaning of time?

ChatGPT

In many cases, the relative pronouns "when" and "that" are interchangeable when following an antecedent involving the meaning of time, but there can be subtle differences in emphasis or clarity.

'When':

Emphasizes the temporal aspect of the antecedent.

Often used when referring to specific moments or periods of time.

May convey a sense of immediacy or time-related context.

'That':

Generally less specific in its temporal emphasis.

May be used more broadly to refer to events or situations.

Sometimes preferred when the antecedent is more complex or when there's a need for clarity or formality.

So, while they can often be used interchangeably, the choice between "when" and "that" may depend on the context, the desired emphasis, and the stylistic preferences of the speaker or writer.
