Update core Open MCT Time API methods

[jvigliotta]

Describe the sustaining activity
Core Open MCT time api methods have been updated and the older ones will be deprecated in the future. We need to update usage in our code.

TimeAPI Method Updates

The following methods in OpenMCT's TimeAPI have been deprecated and should be updated to use their newer counterparts:

1. timeSystem(timeSystemOrKey, bounds) → Split into:

   • getTimeSystem()
   • setTimeSystem(timeSystemOrKey, bounds)

2. bounds(newBounds) → Split into:

   • getBounds()
   • setBounds(newBounds)

3. clockOffsets(offsets) → Split into:

   • getClockOffsets()
   • setClockOffsets(offsets)

4. clock(keyOrClock, offsets) → Split into:

   • getClock()
   • setClock(keyOrClock)
   • Note: Clock offsets are now set separately using setClockOffsets()

5. stopClock() → Replace with:

   • setMode(FIXED_MODE_KEY)

Example Code Update

// Old code
openmct.time.timeSystem('utc', bounds);
openmct.time.clock('local', offsets);
// New code
openmct.time.setTimeSystem('utc', bounds);
openmct.time.setClock('local');
openmct.time.setClockOffsets(offsets);

TimeAPI Event Updates

The following TimeAPI events have been deprecated and should be updated to use their newer counterparts:

1. 'bounds' → 'boundsChanged'

   // Old
   openmct.time.on('bounds', (bounds, isTick) => {});
   // New
   openmct.time.on('boundsChanged', (bounds, isTick) => {});

2. 'clock' → 'clockChanged'

   // Old
   openmct.time.on('clock', (clock) => {});
   // New
   openmct.time.on('clockChanged', (clock) => {});

3. 'timeSystem' → 'timeSystemChanged'

   // Old
   openmct.time.on('timeSystem', (timeSystem) => {});
   // New
   openmct.time.on('timeSystemChanged', (timeSystem) => {});

4. 'clockOffsets' → 'clockOffsetsChanged'

   // Old
   openmct.time.on('clockOffsets', (offsets) => {});
   // New
   openmct.time.on('clockOffsetsChanged', (offsets) => {});

Additional Events

The following events remain unchanged or are new:

• 'tick' - Emitted when a clock tick occurs
• 'modeChanged' - Emitted when the time mode changes (fixed vs. realtime)

Expected behavior
