lcdscreenrename.cpp

// Filename:    lcdscreenedit
// Description: allows editing of a date / time data set (as string) in three different forms:
//              "15.03.2015 10:05-10:07" is start / stop of a timer read from file
//              "15.03.15 10:05-10:07"   is start / stop of a timer by edit
//              "15.03.15  10:05:00"     is system clock
