Can you check few points here -
Please check what is the schedule time on scheduler item? /sitecore/system/Tasks/Schedules/ you can see scheduler item there. Please check start and end date also check the timings as well as on which day it run. Basically compare your schedule field value by briancaos.wordpress.com/.../
Check Last Run field value when it ran last time.
Another way check in log file with the Scheduler Name if that scheduler is firing up or any exception in the code.
It would be great if you can share screenshot for Time Format of scheduler.
