EigrpUpTimeString
Specifies a timer value in days, hours, minutes, and seconds in ASCII format. If the up time is less than 24 hours, the number of days will not be reflected and the string will be formatted like this: 'hh:mm:ss', reflecting hours, minutes, and seconds. If the up time is greater than 24 hours, EIGRP is less precise and the minutes and seconds are not reflected. Instead only the days and hours are shown and the string will be formatted like this: 'xxxdxxh'.
