When adding devices to maintenance schedule on Spectrum and the schedules sync to UIM and I open the schedule in DX IM OC, the timezone is different.
Both servers I have checked and they are using the exact same timezone.
Working as designed
UIM 20.33 - Spectrum 20.2.2 - spectrumgtw 8.69
By default, the maintenance Schedules that are synced from Spectrum to UIM are stored on the UIM DB with timezone = UTC+0, regardless what the Timezone is set in Spectrum.
So whatever time is defined in Spectrum it will be honoured in UIM, but in UIM it will show as GMT/UTC+0 time in the UIM Operator Console UI
