Assistance needed in fixing the time format

[Voyager]

Hi Team,
I have a field "taskpick" in mm/dd/yy hh:nn format and another field "tasktime" in decimal format with 2 decimal points. Here is the issue
1) I need to add taskpick field with tasktime field and get a new field "freeat" which should be in mm/dd/yy hh:nn format

I use the below code but it gives me incorrect answer how to fix it

e.g. Taskpick (01/10/19 11:15) + Tasktime (81.00) gives the answer as (01/11/19 3:10) but I want the correct result as (1/13/2019 20:15)

How can I fix the error in the line ![freeat]

 Do While Not rsTask.EOF
                     .Edit
                        !employee = rsemp!ename
                        ![avlto] = rsemp![avlto]
                        ![freeat] = DMax("[freeat]", "ests", "[Ename]='" & rsemp!ename & "'") + Nz(rsTask![tasktime])

Try

 ![freeat] = DateAdd("h",Nz(rsTask![tasktime],DMax("[freeat]", "ests", "[Ename]='" & rsemp!ename & "'") )

however that does not seem to take into account parts of an hour, so perhaps best to convert to minutes, or even seconds if it has to be that accurate.

 ![freeat] = DateAdd("n",Nz(rsTask![tasktime]*60,DMax("[freeat]", "ests", "[Ename]='" & rsemp!ename & "'") )

you can also use the timeserial to turn hours, min, sec into a time prior to adding.
