VFP supports arithmetic on datetime values. When you substract one datetime from another you get the elapsed time in SECONDS.<\/p>\n
ie:<\/p>\n
datetime(2008,1,1,15,0,0) – datetime(2008,1,1,14,0,0) is 3600\u00a0SECONDS<\/strong>.<\/p>\n However be carefull with datetime arithmetic and round the value to 0:<\/p>\n lnSeconds = round(m.ltEnd – m.ltStart, 0)<\/p>\n<\/div>\n<\/div>\n And here is a little trick for formatting the result as time (in 24hr range):<\/p>\n ? TRANSFORM(RIGHT(TTOC(CTOT(‘0′)+(m.ltEnd – m.ltStart),1),6),’@R 99:99:99’)<\/p>\n<\/div>\n if you are using datetime fields then u can simply use<\/p>\n higherDateTime – lowerDateTime<\/p>\n it will give u result in milliseconds<\/p>\n if you are using time fields then you have to extract hours, minutes (second is u r using) you can extract any part by using substr or left and right functions <\/p>\n VFP supports arithmetic on datetime values.

\nlcTime=TIME()
\nlnHour = val(LEFT(lcTime,2))
\nlnMinute = val(right(lcTime,2))<\/p>\n<\/div>\n<\/div>\n
