I just saw a very strange error happen in a 2.0 M/R script. IT's been running for a few years now with no issues. The script suddenly throw the following error:

Execution Time: 0.00s

Script Usage: 0

Type: Map/Reduce

Function: map

Error: SSS_TIME_LIMIT_EXCEEDED

Script Execution Time Exceeded.

This was the line of code that timed out:

updateValues[fieldId] = new Date();
