basic clock

i made this program.. it ran on ver1.0.5 perfectly but on the new one ie ver1.6.5 it says errors

Update your third-party time library to a more recent version instead of using an outdated library with a new Arduino IDE!

The IDE now has a library manager (with an up to date version), delete your time library, then open the IDE.

Use menu: Sketch->Include Library->Manage libraries...

Search for the Time lib and hit install.

The compiler is telling you that the arrays must be const in order to be stored in PROGMEM. It is not rocket science to edit the file it is complaining about, and add const to the offending line.

If you don't understand how/where, again it is not rocket science to search this forum for that message. The step-by-step instructions have been posted more than once.

thanks all it seems that it needed new library,i deleted he old ones & downloaded new ones
