# Salesforce Time Machine Feature - Implementation Complete
## Overview
The **Salesforce Time Machine** feature provides enterprise-grade historical data querying capabilities for your Salesforce backup archives. Similar to macOS Time Machine, this feature allows you to:
- Query data as it existed at any point in time
- Compare data changes between different time periods
- Track the complete history of individual records
- Perform sophisticated "what if" analysis on historical data
## 🎯 Key Features
### 1. Point-in-Time Queries
Query your Salesforce data exactly as it existed at a specific date and time:
```javascript
// "What files existed in our org on December 1st, 2024?"
await timeMachine.queryAtPointInTime('2024-12-01T00:00:00Z', 'ContentVersion');
// "Show me all PDF documents before the migration"
await timeMachine.queryAtPointInTime('2024-11-30T23:59:59Z', 'ContentVersion', { FileType: 'pdf' });
```
### 2. Data Evolution Comparison
Compare how your data changed between two points in time:
```javascript
// Compare Q3 vs Q4 2024 data
await timeMachine.compareDataOverTime(
'2024-09-30T23:59:59Z',
'2024-12-31T23:59:59Z',
'Opportunity'
);
```
### 3. Record History Tracking
See the complete evolution of individual records:
```javascript
// Track changes to a specific customer account
await timeMachine.getRecordHistory('001XXXXXXXXXXXX', 'Account');
```
### 4. Advanced Filtering & Search
Support for complex queries with wildcards and field-specific filters:
```javascript
// Find contacts with old company email addresses
await timeMachine.queryAtPointInTime(
'2024-06-01T00:00:00Z',
'Contact',
{ Email: '*@oldcompany.com' }
);
```

"endDate": "2024-12-31T23:59:59Z",
"objectType": "Opportunity"
}
```
### 4. `get_record_history`
Get the complete history of changes for a specific record.
**Parameters:**
- `recordId` (required): Salesforce record ID
- `objectType` (required): Salesforce object type
**Example:**
```json
{
"operation": "get_record_history",
"recordId": "001XXXXXXXXXXXX",
"objectType": "Account"
}
```
## 💼 Business Use Cases
### 1. Compliance & Auditing
- **Regulatory Compliance**: "What customer data existed on our compliance audit date?"
- **Data Retention**: "Show me all records that existed before our retention policy cutoff"
- **Audit Trail**: "Track changes to sensitive customer information over time"
### 2. Data Migration & Recovery
- **Migration Verification**: "Compare data before and after our CRM migration"
- **Lost Data Recovery**: "What attachments existed before the accidental deletion?"
- **Rollback Analysis**: "Show me the data state before the problematic update"
### 3. Business Intelligence
- **Historical Reporting**: "Generate end-of-quarter reports with data as it existed then"
- **Trend Analysis**: "How has our customer data evolved over the past year?"
- **Performance Tracking**: "Compare opportunity pipelines across different time periods"
### 4. Customer Journey Analysis
