time decode error since v1.11.13

[jill567]

I'm running a backwards simulation using daily data acquired from Copernicus. On an old version of opendrift (v1.11.13), on an old laptop, it runs with no warnings or errors and produces sensible output. In the latest version, installed on a newer laptop, (v1.13.1), it gives a warning, then it runs the simulation, but at the end, it errors with a sequence of messages, all copied below. My question is whether I can install the older version of the code on the newer laptop? I rummaged for retrospective versions, but couldn't see them here. I can provide more run/data details, but I'm using the same code and input file on both systems.

Grateful for any pointers, Jill
