For the error below, what consists of “a single time loop”? I am having trouble understanding specifically where the 10 minutes starts counting from, and when the 10 minute timer stops counting. Tried searching the docs but was not able to locate the answer.

Runtime Error: Algorithm took longer than 10 minutes on a single time loop. CurrentTimeStepElapsed: 1.0 minutes

When timing my functions, it doesn't really look like I'm reaching 10 minutes total across all functions in any trading day before moving onto the next trading day (it's only at ~3 minutes), so perhaps I am misunderstanding the 10 minute timer.
