In Malaysia, because day and night hours are nearly the same length all year round,there is no need to adjust clocks. The only time I remember the adjusting of clocks was when East Malaysia and West Malaysia synchronized their clocks and that was only 1 or half hour difference ( I forget now), all the way back in 1982.
Some other places on Earth, however, have more daylight in the Summer than in Winter.
Last Sunday, we had to "spring forward" on hour for the spring/summer time and it seems like Henry adapted from Day One. I didn't reset the clocks before we went to bed and so when Henry started making "I need to go out" noises on Monday morning, I got out of bed and looked at the clock - it said 6:45 a.m.
