Add minutes to time.

[rullbandspelare]

Hi!
I know that

Code: Select all

let>bl=1971-03-22
add>bl,10

Gives a correct calculation of dates. I.e bl=1971-04-01

But what about time?
I have tried
let>bl=10:55
add>bl,10

But this gives me an error.

What is the easiest way to add and subtract minutes from a certain time?

Thanks!

If there is no easy way i will try it like this instead. Problem if over midnight , but for my purpose it works.

Code: Select all

//Let>nowshutdown=14:45
//let>addition=18

Separate>nowshutdown,:,time
let>hours=time_1*60
let>totaltime=hours+time_2
let>newtime=totaltime+addition
let>hours={int(%newtime%/60)}
Let>minutes={int((frac((%newtime%/60)-%hours%))*60)}

Use the VBScript time functions:

Code: Select all

VBSTART
VBEND

//add ten minutes to current time
VBEval>DateAdd("n",10,now),new_time

//or add 60 minutes to specific time
VBEval>DateAdd("n",60,"18:30"),new_time

//Get out Hour, Min, Sec portions
VBEval>Hour("%new_time%"),hour
VBEval>Minute("%new_time%"),min
VBEval>Second("%new_time%"),sec
