How to change the clock format on a Samsung Galaxy S2

Are a 24 hour party person or do you prefer to know whether you are in AM and PM? Whether you prefer the 24 hour clock format or the 12 hour format the Samsung Galaxy S2 (and pretty much every Gingerbread Android) allows you to choose which option is shown and with ease you can flick between the two.

By opening the settings screen (press "menu" then settings you'll be able to find the options for "Date and Time" which you'll need to click on. The Date and time menu will look something like the screen shot to the left of this paragraph and as you can see near the bottom is a tick box with the option "Use 24-hour format". By checking the box you'll notice that the clock in the top corner
will do one or two things. Firstly the "AM" (or "PM") will be dropped from the clock (see the screen shot to the right with out the AM). Secondly if you are beyond 12:59 you will notice that the clock is showing in the 24 hour format (for example 16:55 is 4:55 PM).

Although this is a tiny feature that most won't use at all it's a nice addition and allows you that little bit of extra choice to personalise your phones display.
