A time series is a structured sequence of data points indexed in chronological order and recorded at successive, typically equally-spaced time intervals. It represents the human-made convention of organizing observations, measurements, or readings along a temporal axis to enable analysis of patterns, trends, seasonality, and dynamics. Time series are analyzed using methods including autocorrelation, moving averages, spectral decomposition, and state-space modeling, and they serve as the foundational data structure for forecasting, anomaly detection, and signal processing.

A time series IS a specific kind of data structure — it is data ordered sequentially by time, where each value is associated with a timestamp. The removal test confirms INSTANCE_OF: a time series is a kind of structured data organization.

Time series analysis existed first and fed into the concept of concept drift — the idea that data distributions change over time builds on the temporal ordering inherent in time series. Which came first? Time series as a field predates concept drift; concept drift extends time series analysis to address distribution shifts within temporal data.
