Autoblog "Next Check" times have turned red…

I’ve been trying to get the Autoblog plugin in to cooperate with another plugin and one of the methods I tried was changing the time zone of my blog. I guess by default they are set to GMT =0 and I changed it to my appropriate time zone of GMT -5 (EST). That affected both columns (Last Processed and Next Check) by turning all the times to the accurate time (GMT -5) but turned them all red. Then I clicked the Debug button (the add-on option), don’t know if that was the right thing to do, but it got rid of the red text in the “Last Processed” column, but left the Next Check column red.

What do the red times mean and if I need to make any additional changes? Please advise.
