Minutes calculation- RESOLVED

[Silvio.Falconi]

I have two Hour and I need the difference in minutes

sample :

access 10:45
exit 12:33

I tried with

Code: Select all  Expand view

nTimeFrom  := Val(Left(cTimeStart,2)+Right(cTimeStart,2))
      nTimeTo    := Val(Left(cTimeEnd,2)+Right(cTimeEnd,2))
      nMinutes1   := TimeToSec(cTimeStart)
      nMinutes2   := TimeToSec(cTimeEnd)
      nMinutes    :=  (nMinutes2-nMinutes1)
 

But sometimes give me a negative value

Silvio,


// Return the absolute difference between two times in hh:mm:ss format
// in character hours, minutes and seconds (hh:mm:ss).
// TIME_DIFF( "22:40:12", "23:55:17" ) -> 01:15:05
// TIME_DIFF( "23:55:17", "22:40:12" ) -> 01:15:05

( convert to minutes if needed ) !!

Code: Select all  Expand view

function TIME_DIFF(cTIME1,cTIME2)
local  nTIME1, nTIME2, nDELSECS, nHRS, nMINS, nSECS, nSECS1, nSECS2

nSECS1   := (val(substr(cTIME1,1,2)) * 3600) +;
              (val(substr(cTIME1,4,2)) * 60) + (val(substr(cTIME1,7)))
nSECS2   := (val(substr(cTIME2,1,2)) * 3600) +;
              (val(substr(cTIME2,4,2)) * 60) + (val(substr(cTIME2,7)))
nDELSECS := abs(nSECS2 - nSECS1)
nHRS     := int(nDELSECS / 3600)
nMINS    := int((nDELSECS - nHRS * 3600) / 60)
nSECS    := nDELSECS - (nHRS * 3600) - (nMINS * 60)

return right("00" + ltrim(str(nHRS)),2) + ;
":" + ;
right("00" + ltrim(str(nMINS)),2) + ;
":" + ;
right("00" + ltrim(str(nSECS)),2)

I need all to minutes because I must calculate the euro/min

Prueba pasar las horas a minutos y operar

try Val(Left(cTimeEnd,2)) * 60 + val( Right(cTimeEnd,2)) - ( Val(Left(cTimeStart,2)) * 60 + val( Right(cTimeStart,2)) )

Prueba asi:

Code: Select all  Expand view

Function TotMinutos()
local cIniTime, cEndTime, nMnts1, nMnts2, nMntsTotal

cIniTime := "22:30"  
cEndTime := "06:28"  

nMnts1 := Val(Left(cIniTime,2)) * 60  + Val(Right(cIniTime,2))
nMnts2 := Val(Left(cEndTime,2)) * 60  + Val(Right(cEndTime,2))

if cEndTime < cIniTime
   nMnts2 := ( ( 24 + Val(Left(cEndTime,2)) ) * 60 )  + Val(Right(cEndTime,2))
endif

nMntsTotal := nMnts2 - nMnts1

Return msginfo("Hora Inicio " + cIniTime + CRLF+;
               "Hora Final  " + cEndTime + CRLF+;
               "Tot Minutos " + Transform(nMntsTotal,"99,999"), "Total Minutos")

 

Saludos.

Silvio,

just some small changes and You can use any format

Code: Select all  Expand view

MsgAlert( "      Time : 12:12:00   to   16:16:32" + CRLF + ;
                  ""  + CRLF + ;
         "      Time-format : " + TIME_DIFF("H", "12:12:00" , "16:16:32") + CRLF + ;
                 ""  + CRLF + ;
         "      Seconds > 30 are rounded to 1 minute" + CRLF + ;
                 ""  + CRLF + ;
         "      Minutes : " + ALLTRIM( STR(TIME_DIFF("M", "12:12:00" , "16:16:32") ) ), "Time-format or Minutes" )

MsgAlert( "      Time : 12:12   to   16:16" + CRLF + ;
                  ""  + CRLF + ;
         "      Time-format : " + TIME_DIFF("H", "12:12" , "16:16") + CRLF + ;
                 ""  + CRLF + ;
         "      Minutes : " + ALLTRIM( STR(TIME_DIFF("M", "12:12" , "16:16") ) ), "Time-format or Minutes" )


// --------------------------
