time - How to change the separator on the clock?

i'm having following problem: i've set (language support) - regional formats (display numbers etc.) hungarian, format should following:

example:

number: 1.234.567,89

date: 2016. nov 6, vasárnap (name of day, not relevant, here's relevant part:) 10:15:15

my clock however, isn't separated :, ..

so clock displays 9.20.46 atm., instead of 9:20:46.

setting format english solve issue, doesn't know how modify 1 instead, in order separated colons instead of dots? using ubuntu 16.04 lts

you can archive creating custom locale in:

/usr/share/i18n/locales

modify date format using ascii code (change u002e u003a).
compile using localedef
direct lc_time custom locale, restart pc.
