hi,

i get result 36:40

i think it must be 24:40 if you sum the times manually


You have SET("Hours")=12.

With SET HOUR TO 12 you cannot to use CTOT() and TTOC() for compute time diff/summ.

clear
SET HOUR TO 24
timeSum=		CTOT('04:45:00')-CTOT('0:')
timeSum=m.timeSum+(	CTOT('11:30:00')-CTOT('0:'))
timeSum=m.timeSum+(	CTOT('08:25:00')-CTOT('0:'))

? STUFF(TTOC(CTOT('0:')+m.timeSum,2),1,2,;
     STR(INT(VAL(TTOC(CTOT('0:')+m.timeSum,2)))+24*INT(m.timeSum/86400)))
