I am trying to come up with the logic to convert milliseconds to
seconds,minutes, and hours.

This is what I have.
Alright, let me have it. Very Happy

; seconds = milliseconds/1000
; minutes = seconds/60
; hours = minutes/60
; days = hours/24

Ex. 1,514,047 milliseconds

Divide result by 1000,

if less than 1, answer is in milliseconds
if greater than 1 or less than 60, answer is in seconds
if 60 or less than 3600, answer is in minutes
if 3600 or less than 216000, answer is in hours

Yeah, that makes sense, what about it? But IMO, dividing in asm is a pain. I'm too lazy to use asm for anything that needs dividing Smile.

Note sure what you're actually want so I've decided to guess and write this program Razz
Code:
format pe console
include 'win32ax.inc'

      mov     ebx, 1

.loop:
      mov     eax, ebx

      mov     esi, 0
      mov     ecx, 1000
      xor     edx, edx
      div     ecx
      push    edx

      test    eax, eax
      jz      .print

      inc     esi
      mov     ecx, 60
      xor     edx, edx
      div     ecx
      push    edx

      test    eax, eax
      jz      .print

      inc     esi
      xor     edx, edx
      div     ecx ; ECX IS STILL 60 HERE
      push    edx

      test    eax, eax
      jz      .print

      inc     esi
      mov     ecx, 24
      xor     edx, edx
      div     ecx
      push    edx

      test    eax, eax
      jz      .print

      inc     esi
      push    eax

.print:
      push    [strTab+esi*4]
      call    [printf]
      lea     esp, [esp+esi*4+8]

      add     ebx, ebx
      jnc     .loop

      cinvoke system, cmd
      invoke  ExitProcess, 0

strTab dd fmtMs, fmtSeg, fmtMin, fmtHs, fmtDays

fmtMs   db "%u millisecond(s).", 13, 10, 0
fmtSeg  db "%u second(s) and %u millisecond(s).", 13, 10, 0
fmtMin  db "%u minute(s), %u second(s) and %u millisecond(s).", 13, 10, 0
fmtHs   db "%u hour(s), %u minute(s), %u second(s) and %u millisecond(s).", 13, 10, 0
fmtDays db "%u day(s), %u hour(s), %u minute(s), %u second(s) and %u millisecond(s).", 13, 10, 0

cmd db "pause", 10, 0

align 4 ; Just to be safe
data import 
  library kernel32, 'kernel32.dll',\
          msvcrt,'msvcrt.dll'

  include 'api/kernel32.inc'

  import msvcrt,\
         printf, 'printf',\
         system, 'system'
end data    
Output on my PC:
Code:
1 millisecond(s).
2 millisecond(s).

12 day(s), 10 hour(s), 15 minute(s), 41 second(s) and 824 millisecond(s).
24 day(s), 20 hour(s), 31 minute(s), 23 second(s) and 648 millisecond(s).

PS: The code was meant to be straightforward, not size nor speed optimization was attempted.

What you could do is use multiplication and take advantage of overflow.
