Morphology

time + series

The meaning 'a series of values measured at successive points in time' is directly derivable from combining 'time' (when moments occur) with 'series' (a sequence of related items); the first noun modifies the second in a straightforward compositional way. This noun+noun construction is common cross-linguistically (e.g. Spanish 'serie temporal', French 'série temporelle'), so a B1 learner who knows both constituents would very likely infer the intended meaning.

Etymology

Time series is a literal name: imagine dots or numbers in a row along a line that shows time, so you can see how something changes. The word series means 'a set in order' and with time it means 'measurements taken one after another', so the phrase means 'a list of values recorded over time'.
