I don't have the IATA manual itself, but judging from the data, it (understandably) gives times of change for airport schedules. In the Soviet Union, airports and train stations all ran on Moscow time, and the old IATA tables reflected this. It's conceivable that the tradition of (airport time) != (ordinary civil time) persists in parts of the ex-Soviet Union, though I'd be surprised if the difference was merely what time of day to move the clocks. In general, when there are multiple, disagreeing times used at the same location, I've tried to use the most popular one. Here it'd presumably be ordinary civil time and not airport time. In other cases I don't know which time was more popular (for example, Tokyo from 1948 to 1951) so I've had to guess. For Estonia and Latvia I have more faith in your relative's direct experience than in the IATA's tables, and my next proposed patch will reflect this.
