Convert milliseconds to seconds - Time Conversions Online calculator to convert milliseconds to seconds (ms to s) with formulas, examples, and tables. Our conversions provide a quick and easy way to convert between Time units. The known data: Your computer's time: equals milliseconds since -- the start of in your time zone ( ). Convert a millisecond value to a date string this (milli )second time number: is the equivalent of this date string in time zone Date to milliseconds converter a date string examples: 'Mon Jun 18 2007 00:00:00 GMT-0400' or ' or ' 9:45:00' What date would that be? Your computer's time: equals this date: A temporal value converted to milliseconds equals so many (milli )seconds: Milliseconds converted to a temporal value So many (milli )seconds: equals so many: How much time between now and then? Your computer's time: and this date: examples: 'Mon Jun 18 2007 00:00:00 GMT-0400' or ' or ' 9:45:00' are so many apart: How much time between now and then (using a millisecond date value)? Your computer's time: and this date in (milli )seconds: are so many apart: Date and Time Math Across Timezones Date and Time Plus/Minus Quantity of Time This date and time in timezone so many equals this date and time in this timezone Date/Time Subtraction This date and time in timezone minus this date and time in timezone equals so many. @craigster's answer is useful if you want just the number of hours or the minutes or the seconds represented by the milliseconds. If you want all three, you need to do a bit more arithmetic. For instance, 23 hrs 59 mins 55 seconds: (23 * 60 * 60 * 1000) + (59 * 60 * 1000) + (55 * 1000) = 86395000 milliseconds To convert 86395000 back into HH:MM:SS you could do: hours = int(duration_in_milliseconds (60 * 60 * 1000)); mins = (duration_in_milliseconds (60 * 1000)) mod 60; secs = (duration_in_milliseconds 1000) mod 60; #hours# #mins# #secs#. All you have to do is divide it. Duration_in_milliseconds / 1000 = Seconds duration_in_milliseconds / 60000 = Minutes (duration_in_milliseconds / 60000) / 60 = Hours In Coldfusion Code it might look like this If you want Hours use this line If you want Minutes use this line If you want Seconds use this line. Quite keen to hear from the person who downvoted this.? Not enough detail? I didn't think that reproducing the code made sense, and also thought it would be patronising to explain how to mod the code to work from milliseconds instead of seconds. The main gist of my answer was to not write one's own routine if a routine which does what one wants already exists. The lesson - and a good one for most CF developers - is 'see what's already out there; don't repeat what others have already done. – Jul 9 '14 at 20:11. Msc nastran manual.
