Set your Raspberry Pi up to match your regional settings.
To change the language used by NOOBS, you can either press the L key on your keyboard, press the up/down arrows to choose the language you want, and then press Enter; or you can do the same thing using the mouse. NOOBS will remember your selection, and will use the same language again next time.
Alternatively, you can pre-select the language before booting NOOBS for the first time. See here.
If you've installed Raspbian using NOOBS, it should automatically pick up the same language you were using within NOOBS. But if you want to select a different language, or if you've installed Raspbian from a standalone image, use raspi-config.
To change the keyboard layout used by NOOBS, you can either press the 9 key on your keyboard, press the up/down arrows to choose the keyboard you want, and then press Enter; or you can do the same thing using the mouse. Note that changing the language (as described above) may automatically change the keyboard layout as appropriate too. NOOBS will remember your selection and use the same keyboard layout again next time.

No part of NOOBS uses the time; consequently there is no option for changing the timezone.
Once again, this is something you can change using the raspi-config tool.
