Timer events not working

None of my Simple Lighting timer events are working. I have a Simple Lighting rule that turns on a light when a contact is opened, and it works OK. I have 2 other Simple Lighting rules that turn an outlet on and off at specific times. Those have not worked for a few days. I updated the hub this morning, and the timer events are still not working. Manual controls work OK....via voice command through Google Home and in the dashboard. Has my hub somehow lost track of time? I looked at the event log on one of the them, and it said the next event was scheduled for the year 2023.
