Convert Time Given in Seconds to Minute, Seconds, Milliseconds

Hi all,

I am trying to convert a time given in seconds such as 183.55s into minute, seconds, milliseconds.

For minute, I'm using: init_mn=fix(init_time/60), which gives me the correct answer.

How can I obtain the seconds and miliseconds without rounding?

Thank you in advance!

This is simply a straightforward format change:

t = seconds(183.55)

t = duration
   183.55 sec

t.Format = 'hh:mm:ss.SSS'

t = duration
   00:03:03.550

producing the desired result.

Read about datetime and hms.

Answer 3

[h, m, s] = hms(duration([0 0 183.55]))

h = 0

m = 3

s = 3.5500

% for sec and fractional sec
si = floor(s)

si = 3

sf = s-si

sf = 0.5500

If you really need minutes (i.e. and not roll-over to hours for >59 minutes) then you can calculate this yourself, e.g.:

inp = 7654.321; % time in seconds
t_min = ceil(1000*inp);
t_ms  = mod(t_min,1000) % milliseconds

t_ms = 321

t_min = fix(t_min/1000);
t_sec = mod(t_min,60) % seconds

t_sec = 34

t_min = fix(t_min/60) % minutes

t_min = 127
