After analysing the screenshot, it seems that system time was wronlgy set (top right corner). If it will be Ubuntu-Clock fault, then the time between Clock and System clock will be different.

I remember setting the time zone to "Edinburgh" when setting the phone. Today, when I opened the clock app I've seen this [1]. You can also notice that time for Warsaw is correct. Then I went to time and date settings. It displayed "UTC+0". I set "Time zone:" to Edinburgh again. After that it showed "UTC+1" and time was correct. I must add that yesterday I set alarm on another device (Android phone) which thankfully woken me up on the right time. Otherwise my son's football training would be missed.
