[VBScript] Helping out with DateDiff

Another from helping out at Automate Excel In Vbscript... ( Vbscript )

Please tell me how to subtract to time values. eg: 10.15 AM - (minus)8.30 Am Using example explain me

The DateDiff function is the one to use in this case. Using your data

a = "10:15 AM" b = "8:30 Am" c = datediff( "s", b, a ) ' the seconds between the two times c = datediff( "n", b, a ) 'the minutes between the two times (because "m" stands for months) c = datediff( "h", b, a ) ' the hours between the two times
