Our convention has been that if clocks are the same all year round and 
if this appears to be permanent, the isdst flag is zero even if the time 
zone's official name includes phrases like "daylight" or "summer".

Admittedly it's sometimes hard to tell whether a setting is permanent, 
but nowadays my impression of typical usage is that the time in Moscow 
is called simply "Moscow time"("Московское время"), which suggests that 
it's OK for the isdst flag to be zero there.
