- Local time as a decimal hour
- 5.0000
- Date shift 1 means the local date is the next day; -1 the previous one.
- 0
- Time in the other zone
- 12:00:00

- UTC hour = 12
- UTC minute = 0
- Other zone offset = 0
- Working day starts = 9
- Working day ends = 17
- offset = -7 = -7
- utc_decimal = 12 + 0/60 = 12
- Local time as a decimal hour = mod(12 + -7, 24) = 5
- Local time in UTC-07:00 = 5 * 3600 = 18 000
- Date shift = floor((12 + -7) / 24) = 0
- other_local = mod(12 + 0, 24) = 12
- Time in the other zone = 12 * 3600 = 43 200
- Hours ahead of the other zone = -7 - 0 = -7
- overlap_start = max(9, 9 + -7) = 9
- overlap_end = min(17, 17 + -7) = 10
- Overlapping working hours = max(10 - 9, 0) = 1
- Offset in minutes = -7 * 60 = -420
Values are shown to six significant figures here; the arithmetic itself runs on exact fractions and is only rounded where a number is printed.

The formula
- local time = UTC + offset, wrapped into a 24-hour day
- the date shifts when the wrap crosses midnight
- working overlap = the intersection of the two working days once shifted
This is a fixed offset. Many places observe daylight saving for part of the year and shift by an hour, so check whether the zone is on standard or summer time.
Offsets are not all whole hours. Nepal is 45 minutes off, India and Iran 30, and a few Australian zones are stranger still.
