Date and Time no longer "Undefined"

Free downloads, free blogger template downloads, free............. That's what always catches our eye when we search for downloads. But like always there is and always was a hidden catch to it.
The other day I downloaded a theme from a blogger template sharing website. It was a really beautiful one and a friend of mine liked it. After uploading the theme we got a stupid error where the date is to be. It was showing undefined instead of the date. I was so curious about it. Went through the entire code wondering where the error was. Damn. I couldn't find it at all.
Lol. It was such a joke when I went back to the site and saw that it wasnt only me who was gettin the error. And guess why the error.
All I had to do was to change the format of the Time Stamp format in the Setting tab. Was in such a mood to bang my head somewhere. Went throught the entire code so minutely wondering where someting was missing for a 15 seconds job.
