  • (2019-05-31) Please add the options to time seconds as well, every second counts; also the option to count from a day to another. I like the simplicity of this, but it is a little too simple hehe.
  • (2018-06-06) Ciaran Maguire: This is a simple but great extension, does exactly what it says
  • (2017-03-16) Alan Sampson: Useless
  • (2017-03-06) Ivn Lns: This is exactly what i was looking for. It just calculates shift times for you, for example (09:45 to 13:20 + 16:10 to 21:40) = 9h 5m!
  • (2015-11-20) G. Deoudis (Sky Feather): It's only for adding time, NOT for subtracting time. Also returned an error saying something about 24 hrs. I added 3 simple times to test it and I got an error back...
  • (2015-02-05) River Atkinson: for calculating time it was awful. you couldn't add more than 2 times together, and you could only add. you cant add things like 33:53 (33 minuets, 53 seconds) also, im the only one who has reviewed this and i gave it one star, and yet it still shows up as 5 stars. this guy hacked it or something.

  • (2019-06-24, v:3.1) Stephen Giraud: Adding time
    I have 4 shifts to add. I put in a time and it requires an AM or PM? I am in add time side. I can't get it to add times together. I really want it to work, I hope you keep working on it. Thanks!
  • (2017-07-18, v:3.1) Unable to enter 24 hour times when editing field
    It is impossible to enter 24 hr time formats after having put a value in for a time section already. Under the Shift Calculator in the first field: Put 13:(don't put second part yet, though it doesn't matter and happens regardless). Reselect the 13 portion. Try to put in 14. Notice it will enter 01 and then change to 04 on each keypress. Using the x on the side does not reset anything in this regard.
  • (2017-07-18, v:3.1) There are AM/PM fields for Just Time
    There shouldn't be any AM/PM fields for Just Time, since it is adding up the amount of time segments provided. i.e. 1:30 + 1:40 = 3:10
  • (2017-07-18, v:3.1) AM/PM data field makes no sense
    The extensions seems to only take 24 hour formats, which means the AM/PM fields are unneeded.
  • (2015-04-25, v:3) Christie Borg: Do not let you add time
    do not let you add time!!! this extension is useless. however it is a really useful extension if it works perfectly!
