The function takes a string parameter of the format YYYY/MM/DD HH:MM or YYYY/MM/DD. And it returns the date/time value (OLE format).
If the string was empty it returns 0 and if the format was wrong it returns -1, so can you can differentiate between no date/time specified and wrongly entered date/time.
I used YYYY/MM/DD, since this is less ambiguous (i.e. won't get mixed up with US and European formats, DD/MM/YYYY and MM/DD/YYYY). The time is optional. The time is assumed to be 24 hour clock.
It's not perfect, but better than nothing.
- Code: Select all
function getDateTime(s)
if #s > 0 then
local yyyy, mm, dd = string.match(s, "(%d%d%d%d)/(%d+)/(%d+)");
local h, m = string.match(s, "(%d+):(%d%d)");
if yyyy and mm and dd and h and m then
return core.datetime(yyyy, mm, dd, h, m, 0)
elseif yyyy and mm and dd then
return core.date(yyyy, mm, dd);
else
return -1; -- Error case, mal-formatted date/time
end
end
return 0; -- No date/time specified
end
