DateTime error

Hello, I tried to run the example on the "DateTime" library. I got an error on the line: " Serial.print( TIME_HEADER,BYTE);"

The error message was: "'BYTE' is no longer supported". Can some one help me with this problem ??

Can some one help me with this problem ??

Yes. Google can. This "error" has been discussed far too many times, because people won't search.

The documentation for Serial.print() lacks any mention of a BYTE format parameter. http://www.arduino.cc/en/Serial/Print So it's a simple case of failure to read the documentation. You don't even need Google to do that.
