Datetime Object - incorrect format

esferatec

It seems that the date and time format does not adapt to the “os.setlocale”. In the following example, the date and time are displayed by os.date() and by sys.Datetime - os.setlocale is used to switch to a different country. In label1 the US format is used and in label2 it remains with my system setting (Germany). It seems that sys.Datetime does not take the current os.setlocale into account.

local ui = require "ui"

local win = ui.Window("date time sample", 320, 200)

local label1 = ui.Label(win, "", 130, 10)
local label2 = ui.Label(win, "", 130, 80)

os.setlocale("English_United States.1252", "time")

label1.text = tostring(os.date())
label2.text = tostring(sys.Datetime())

win:show()

repeat
	ui.update()
until not win.visible

In fact it's not a bug, as the Datetime object use current Windows system locale, not the current C runtime locale (used by os.setlocale()).

It should be easy to add custom locale support for the sys.Datetime object, I will check this.

Thank you for your answer. I think it is enough if this is made clear in the documentation. Here it says: “The format string depends on the current user locale, using the standard short format.” Maybe you can replace "current user locale" with current Windows system locale".

The alternative is to use “os.date()” if you use “os.setlocale". That's fine with me. Thanks for your help as always.
