[en] since + various tenses

[rillig]

LanguageTool accepts all of the following sentences, while I believe that some of them are wrong.

• Since yesterday, it will not rain anymore.
• Since yesterday, it has not rained anymore.
• Since yesterday, it does not rain anymore.
• Since yesterday, it would not rain anymore.

Mixing up the English tenses is typical for Germans, therefore LanguageTool should warn about mistakes like these.

The original sentence I dealt with is about programming, and it goes:

Since C99, these implicit declarations are not allowed anymore.

Hi @rillig, this is a notoriously difficult subject, especially if you want to write a rule that's useful to language learners without massively enervating the native speakers. Native speakers are very unlikely to get a verb tense wrong (as in simple past vs. present perfect), and there can be contexts warranting all four tenses you mentioned. The original text you mentioned seems correct, btw.

• Since 9-11, TSA will arrest you for making WTC-related jokes around an airport.
• Since 9-11, there have been many increased security measures.
• Since her father died of lung cancer, she does not smoke any longer.
• Since the expensive TV broke right after she set it up, she would never buy electronics at Target again.
