Time comparisons are most reliable when they use a named regional time zone and a specific date, because UTC offsets can change.
What daylight saving does
Daylight saving time moves local civil clocks forward for part of the year. This usually creates more evening daylight by the clock, although policies and dates differ between jurisdictions.
The UTC offset changes
When daylight saving starts, a location is generally one hour further ahead of UTC. When it ends, the offset returns. This means the time difference between two cities can change during the year.
Not every place changes
Many regions do not observe daylight saving. Queensland, for example, remains on Australian Eastern Standard Time while New South Wales changes seasonally. Always compare named zones for the date that matters.
