　　Here is some information about making international phone calls．

　　You can now phone any country in the world although in some cases you can only call major cities．When you can’t make direct dialing(直拨)calls you can ask the international operator to help you．This is more expensive and takes more time but it may be helpful if you want to speak to a particular person and no one else; in this case you should ask for a “person-to-person” call．Even more expensive is a reverse charge call where the person who receives the call pays．

　　If the international line is busy you can reverse a call; explain the number you want the operator will call you back when the line is free．

　　You can save money by calling outside office hours e．g．early in the morning late at night and on Sundays．

　　Remember that the time may be different in the country you are calling．International time is based on GMT(Greenwich Mean Time); London is on GMT and Moscow．For example is 3 hours ahead．

　　There is one problem：change to DST(Daylight Saving time)for the summer．In the UK clocks are put forward one hour in spring and put back in autumn and so London is actually one ahead of GMT in the summer．
