There are several sites where you can find information about local time.
Just search GOOGLE for words like "time zone convertor". Each site will requere the separate approach. Here is an example from where you can borrow ideas.

do yLocalTime with "Moscow"

Procedure yLocalTime
LPARAMETERS lcCountry_or_City

clear
READYSTATE_COMPLETE =4
MAX_TIME =30

lcCountry_or_City=upper(lcCountry_or_City)

if not (type("oIE")="O" and not isnull(oIE))
	oIE = CreateObject("InternetExplorer.Application")
endif
oIE.visible=.t.

lcURL="http://www.timezoneconverter.com/cgi-bin/tzc.tzc"

lcURL=lower(lcURL)
oIE.Navigate(lcURL)

do while oIE.Readystate <> READYSTATE_COMPLETE
	wait wind time 1.0 ""
enddo

lcInnerText = upper(oIE.Document.Body.InnerText)


*case lcUrl="http://www.timezoneconverter.com/cgi-bin/tzc.tzc"
	* find Region designation
	ln=occur(lcCountry_or_City,lcInnerText)
	if ln<=0
		=messagebox("Country/City "+lcCountry_or_City+" not found!")
	else

		lcsubstr=left(lcsubstr,at("/",lcsubstr,2))
		lcRegion=strtran(lcsubstr,"/"+lcCountry_or_City,"")

		if not empty(lcsubstr) and not empty(lcregion)
			lcURL=lcURL+"?now=1&zone="+proper(lcRegion)+;
			+proper(lcCountry_or_City)+"&tozone=GMT"

			oIE.Navigate(lcURL)

			do while oIE.Readystate <> READYSTATE_COMPLETE
				wait wind time 1.0 ""
			enddo

			lcInnerText = oIE.Document.Body.InnerText
			lcmessage= left(lcInnerText, at("in "+proper(lcRegion),lcInnerText)-1)
