As the writers often choose to use rules from English as it is spoken and written in the Commonwealth, "days time" with no apostrophe is probably intentional, and correct. It is not time that belongs to days; it is days as a measure of time. Here is an excerpt from the Australian Government style manual:

Australian Government Style Manual: Apostrophes

I disagree with those examples being equivalent – the first two are describing a person's state (he has been retired for six months, she is five months pregnant) but the event is in a few days' time – which I would take to be "the [amount of] time of a few days" rather than "a few days [of] time". The apostrophe indicates that the days possess that amount of time.

The also Australian and government-run ABC (Australian Broadcasting Corporation) style guide takes this stance:

If a period of time modifies a noun, use an apostrophe: he was sentenced to 10 years’ jail, she is taking six weeks’ holiday. Or rewrite the phrase: he was sentenced to 10 years in jail, she is taking six weeks off. No apostrophes when the time period is adverbial: two weeks old, six months pregnant.
