Segment MetaData mismatch between API's

The Creation Time Millis value received for a realtime segment from `/segments//metadata` API is not aligning with the value received from`/segments///metadata` API . I assume they denote the time when the segment started consuming .

Value received for a segment from `/segments//metadata` :
```
{
"segmentName": "segment_name",
"schemaName": null,
"crc": 1641778138,

Value received the same segment from `/segments//metadata` :
