What are the best times to cold call potential sellers?

[George Steers]

Hello. I have a huge list of potential sellers that I am beginning to cold call. Most of the research that I have done says to call between 9-11 in the morning and then 3-5 in the afternoon. While I have done plenty of cold calling in my past life in sales, it has always been business to business. 

Also, I'm wondering if the previously listed hours may be outdated as most people have cell phones and work during the day. 

Does anyone have any thoughts about this? 

Cheers and thank you, 

George
