What does this と do here?


I suspect this question to be very simple but nevertheless, I don't understand
why と is used here (in particular why not が or の (with the meaning of が)?)

> 交通事情により、表示の時刻 **と** 前後することがあります。




This 「と」 indicates the **_standard for comparison_** (and how something can
deviate from that standard).

Standard: [表示]{ひょうじ}の[時刻]{じこく} "Times displayed"

Possible deviation: [交通事情]{こうつうじじょう}により[前後]{ぜんご}する "May not arrive/depart on
time due to traffic condition"

> 「交通事情により、表示の時刻と前後することがあります。」

In this sentence, the subject for the verb 「前後する」 is unmentioned. The subject
is **_not_** 「表示の時刻」, which is why one cannot use 「表示の時刻 **が** 」 as you
suggest.

The unmentioned subject here is the " ** _actual arrival/departure times_** ".
It is saying that those may deviate from the 「表示の時刻」.

The phrase to look for is 「A + が/は + B + **と** + （前後する）」 and in this case, the
"A + が/は" part is left unsaid.
