can confirm that these are typically manually changed for daylight savings as most places don't observe that archaic bullshit, or can change on a whim.
to illustrate this point, for Russia: On 27 March 2011, clocks were advanced as usual for daylight savings, but they did not go back on 30 October 2011, effectively making Moscow Time UTC+04:00 permanently. but, then, On 26 October 2014, following another change in the law, the clocks in most of Russia were moved back one hour, but summer Daylight Time was not reintroduced; Moscow Time returned to UTC+03:00 permanently. This is only for Russia over the past 10 years. Now multiply that times every country in the world.
which is why clocks of this nature are typically manually updated.
On 26 October 2014, following another change in the law, the clocks in most of Russia were moved back one hour, but summer Daylight Time was not reintroduced; Moscow Time returned to UTC+03:00 permanently.
This is why the premise of OP's photo is incorrect. The changeover was not this past March, it was 2014.
Occam's Razor would tell us that this simply is just a screwup of whoever is manually setting those clocks.
