Verdikt takoj, chto imenno sam perehod vremeni rabotajet kak ozhidajetsja! Kogda menjajetsja odin denj na drugoj,
promezhutok ne obrivajetsa.
No! Pri statuse "normal maintenance", soobschenija vsje-ravno otpravljajutjsa, esli tam trigger s oshibkoj.
I takzhe ne rabotajut promezhutki, kotorije dlinneeje odnogo dnja. Oni obrezajutsja, to estj s pervogo dnja na vtoroj maintenance perehodit,
no na tretij uzhe net.
