GRB 210217A: a short or a long GRB?

Gamma-ray bursts are traditionally classified as short and long based on their $T_{\rm 90}$ value (the time interval during which an instrument observes $5\%$ to $95\%$ of gamma-ray/hard X-ray fluence). However, is dependent the detector sensitivity energy range in operates. As a result, different instruments provide values for burst. GRB 210217A detected with duration by {\it Swift} Fermi}.
