To access the settings for the plugin you click on the toolbar icon on the main window. Behind this there are a number of windows as described below.
Plugin Preferences
Max Alarms before scrolling window: how many alarms does the list grow to before turning on the scroll bar;
Hide Alarm Clock when game is paused: when you open the Pause menu should the alarm windows be hidden – does not affect the F2 behaviour where all the interface is hidden;
Show Tooltips on Mouse Hover
Time Format: Toggle the displayed times/dates between UT (raw seconds), KSP formatted dates and standardised date format ('1,234s' or '2h, 10m, 35s' or '02:35:20'). Same as clicking the World Date/Time in the footer;
Allow Ship Jump...: This toggles the visibility of the Jump to Ship buttons in alarms displayed on the Space Center and Tracking Station Screens. This option is here as the use of this function saves your game to a temp file then reloads it to start at the new ship. People who are uncomfortable with this functionlity should disable this option.
Save File Backups
This setting causes the KAC to backup the current saves prior to switching vessels, in all three game modes where jumping can be done. It copies the current persistent.sfs and quicksave.sfs files to KACBACKUPyyyyMMddHHmmss in the current save game, and if any of the backup code fails then the KAC will abort the ship switch.
You can configure how many saves to keep in the archive. And whether to fail the ship jump if the backup fails when in flight mode (in view mdes the backup is part of the jump so if it fails you can't jump)
Time Warp/Math Checks This setting controls how often the alarm clock recalculates and checks for upcoming alarms in the background. You can choose from one of the presets of choose Custom. Custom reads the value from the config.xml file as per below (insert line if needed:
<int name='BehaviourChecksPerSec_Custom'>40</int>
Default Alarm Settings
Alarm Position: where on the screen you want new alarms to be displayed initially;
Alarm Action: When an alarm fires do you want the Alarm Clock to affect the Warp or Pause activities;
Default Margin: Set a default for how long before an event an alarm will fire;
Delete Alarm on Close: Set a default for this checkbox on each new alarm;
Alarm Specific Settings-1
Detect and Add Alarms for SOI Change
Throw Alarm on background SOI Change: Checks on all vessels and monitors for a change in the name of the SOI body;
Alarm Action: Action for the Auto-Added SOI Alarms;
Alarm Margin: Margin for the Auto-Added SOI Alarms;
Transfer Alarms
Auto Recalc of Transfer Points: This setting causes the Kerbal Alarm Clock to monitor Transfer alarms and recalculate the time of the target phase angle. This is required as the forumla's are all based on circular orbits, while most are elliptical. I do not recommend turning this off unless you are having issues with these alarms;
Auto Recalc of Node Points: This setting causes the Kerbal Alarm Clock to monitor Node point alarms and recalculate the time of the alarm;
Alarm Specific Settings-2
Detect and Add Alarms for Maneuver Nodes: Will automatically add alarms for any future Man Nodes
Remove Auto Alarms is Man Node Removed: Pretty self explanatory;
Threshold: This setting dictates that if a new man node is discovered within this time period from the current time then it will not create a new alarm
Alarm Action: Action for the Auto-Added SOI Alarms;
Alarm Margin: Margin for the Auto-Added SOI Alarms;
Crew Alarms
Store Man Node/target with Crew Alarm: This sets the default behaviour for any new crew alarms;
This tab lets you control on what screens the Alarm Clock will be visible and the location of the icon on each of these. The Window position and state is saved separately for each scene. NOTE: If you turn off the visiblity in the Space Center or Tracking Station you can always access this tab via Flight mode to reenable the alarm
