An American who found himself in Moscow wanted to know the time. He saw a man approaching him, carrying two heavy suitcases  and asked the fellow if he if knew the correct time.

'Certainly,' said the Russian, setting down the two bags and looking at his wrist. 'It is 1 1:43 and 17 seconds. The date is Feb 13, the moon is nearing its full phase and the atmospheric pressure stands at 992 hectopascals and is rising.'

The visitor was dumbfounded but managed to ask if the watch that provided all that information was Japanese.

'No,' he was told, 'it is our own ,a product of Soviet technology.'

'Well, that is wonderful, you are to be congratulated.'
"Yes,'the Russian answered, straining to pick up the suitcases, 'but these batteries are still alittle heavy.'
