by the time + CLAUSE

The phrase ‘by the time‘ is used with clauses to say that something has already happened at the time that something else happens.

Let’s look at simpler examples of the same meaning with a noun phrase:

By my 18th Birthday, I will know.

With a clause:

By the time I am 18, I will know.

It basically means I will know before the time of my birthday.

*Note that the tense may seem unusual because the present form ‘I am‘ is used even though the birthday is in the future.  Similarly, here is an example using by the time + present simple tense + future clause:

By the time it lands, they will already know if anything needs to be serviced.

There is no other EGP tense that is related to this particular complex time conjunction or an English Vocabulary Profile entry.  The question is what CEFR level is the use of other tenses and structures?  The closest meaning in the EVP is:

A2  not later than; at/on or before

She had promised to be back by five o’clock.
The application must be in by August 31st.

but the example above is a simple preposition…

So at C1, the present simple can be used for a future meaning, at A2 a very basic version of the meaning can be used, but there is no listing for the ‘by the time’ in the EVP.   The Oxford Phrase List does mention ‘by the time (that) …‘ at B1.

For this reason, we will say that using ‘by the time‘ as a complex time conjunction with clauses is at least B2.

Here are past simple examples that we consider to be at least B2 complexity:

By the time that I realized he wouldn’t be able toI tried to leave.

Looking through the PELIC corpus the majority of the uses of the structure contain errors.  This means this is highly unlikely to be producible at lower levels.  Here is a correct use of tenses which we have corrected a few other minor errors in from the PELIC corpus:

We didn’t need to buy some small things to live here because by the time we arrived in Pittsburgh, 

our stuff such as kitchen goods, bath goods, clothes, and stationery had been shipped to my husband’s friend’s apartment.
