Adding timestamps to the log output for time steps

Hi,
Is there a way to get COMSOL to report the time stamp for log entries during a time marching simulation? I know I get it on the Start/Finish of a step in the sequence but something more granular would be helpful. I am wondering if I'm missing a checkbox, though I did specify "detailed log" in the options. I'm running a longer simulation with a lot of timesteps. . The matrix is large enough that I don't want to wait around with a stopwatch, but I'd like to know the approximate solve time to get an ETA for it finishing, know if it's stalling, or make some wall clock estimates. It would be really nice to have a time stamp associated with each step.
Right now I see somethign like:
Time t = 0.123 Iter SolEst Damping StepSize #Res #Jac #Sol LinErr LinRes 1 1.2 1.00 0.061 1123 1124 1123 6e-9 4e-11 Solution error estimates for fields: etc, etc 2 1.1e-13 1.000 1.1e-9 1124 1125 1124 2e-8 3e-9 Solution error estimates .... Step Time Stepsize Res JAc Sol Order Tfail NLfail LinErr LinRes 511 0.123 0.015 1125 1126 1125 2 4 0 2e-8 3e-9I'd love to be able to get a timestamp either at the start or end of a major (or minor) timestep, something like:
Time t = 0.123 (2023-08-25 09:22:37 UTC) Iter SolEst Damping StepSize #Res #Jac #Sol LinErr LinRes 1 1.2 1.00 0.061 1123 1124 1123 6e-9 4e-11 Solution error estimates for fields: etc, etc 2 1.1e-13 1.000 1.1e-9 1124 1125 1124 2e-8 3e-9 Step Time Stepsize Res JAc Sol Order Tfail NLfail LinErr LinRes 511 0.123 0.015 1125 1126 1125 2 4 0 2e-8 3e-9Or
Time t = 0.123 Iter SolEst Damping StepSize #Res #Jac #Sol LinErr LinRes 1 1.2 1.00 0.061 1123 1124 1123 6e-9 4e-11 Solution error estimates for fields: etc, etc 2 1.1e-13 1.000 1.1e-9 1124 1125 1124 2e-8 3e-9 2023-08-25 09:22:37 UTC Step Time Stepsize Res JAc Sol Order Tfail NLfail LinErr LinRes 511 0.123 0.015 1125 1126 1125 2 4 0 2e-8 3e-9Is there something I'm missing? I'd rather not have to add a method call into the solver process to do it. I've toyed with creating a probe that calls out to Java's Timestamp(), but that also feels like a huge workaround.
Thanks, Peter
