Log time
Clock in
Where
Break and mileage are asked when you clock out. Overnight can be set either here or there — whichever you know first.
Clock out
An unpaid break shortens the paid time by that much.
Pause for
The timer stops and the job is held. Paused time is not paid, and nothing is running — so you can clock in on a different job and come back to this one afterwards.
Back-fill past logs
Load a TimeSheet Pro export into your own log. Nothing is written until you have seen what it would create, and re-importing the same file is safe — rows that already exist are skipped, not duplicated.

Paste the airline's confirmation email, or the calendar invite attached to it. A booking reference on its own cannot be looked up — it belongs to the airline that issued it.

Send to HR
Fills the T-100-100 HR issued and downloads it. Worth checking the figures first — this is the version that gets read.
Expected pay
An estimate, not a payslip. Shown only when pay figures are switched on in Settings.
Jobs
Hours, entries and mileage per job. Jobs themselves are created and edited in Kimai — including the order number that becomes the job code.
Blank forms
Each form covers a fixed run of periods. When yours runs out, upload the next one here and Muster picks it automatically — nothing else to change.
Used by the “Not worked” button that appears on Saturdays and Sundays. Set 0 to hide it.
The day you began recording in Muster. Earlier days are drawn as a standard week — 8.5 h Monday to Thursday, 5 h Friday, which is the 39 — hatched, and counted in nothing. They never reach the timesheet or the pay figures.
Two-letter codes, comma separated. Everywhere else gets the overseas rate. Jersey (JE), Guernsey (GG) and the Isle of Man (IM) are not part of the UK — add them here if your employer treats them as such.
What you earn is the one genuinely personal thing here. With this off, the figures are never calculated and never leave the container — the hours still check exactly as before.
Mon–Thu 06:00–08:00 and 17:30–22:00 only. Non-contractual and at manager discretion.
Siga Vision phone cover, Saturdays, Sundays and bank holiday Mondays. Hides the Standby cover activity when off.

Hours above this in a Monday–Sunday week are overtime.
The column on the T-100-100 those hours are claimed in.
Every Sunday hour, whether or not the week passed the threshold.
Bank holiday hours sit outside the week and are claimed in this column.
On: travel hours push you toward the threshold and are paid at whatever the week earns. Off: they leave the week and are claimed separately in Travel x1.0.
Travelling on a Sunday can be worth less than working on one. Leave this as the Sunday column unless the agreement carves it out.
The payroll period runs from this day of the month to the day before the next one, so 11 means the 11th to the 10th. It is not free: HR’s workbook has one sheet per period, and days outside that sheet have nowhere to be written. The export still runs and says so at the top, loudly — a right period and an out-of-date workbook is a real situation, and only you can say which is wrong. 1 to 28, because a boundary that moves in February is not a boundary.
A choice, not something Muster knows — the form states no multiple for a worked bank holiday. Off claims the hours in the Bank Hol column; on claims them at plain rate and records a day owed, which is claimed in Cezanne and never on this timesheet.
What you are contracted to work each day. A weekday with no entry is assumed at contract, so the week is not read as short.
A light screen for working outside. Not automatic — a phone’s dark mode follows the clock, not the weather.

Muster handles the working day. Kimai is still needed for six things: creating jobs and customers (including the order number that becomes the job code), creating activities, issuing API tokens, your password, tidying tags, and bulk edits.
