I am a jailbreak n00b but I'm trying to figure out how I can add a few towns/cities to the default/stock Clock app on my iPhone. After a bit of research, I tried looking into /usr/share/tz_map.plist and /var/stash/share.khbq2d/CSI/tz_map.plist, but haven't had any success. I just want to add a few cities/towns in the EST/GMT-5 time zone.

Also, I'm using iFile... I haven't learned how to use open SSH yet, should I be doing that?
