DataParser: Enable parsing if 0 or 1 timestamps are received

[nitin710]

Description

The parser should be able to handle a case when 0 or 1 timestamps are received.

Case: when 0 timestamps are received

• e0 = first timestamp in recorded file
• e1 = last timestamp in recorded file
• The created timeline maps emotibit timeline -> epoch timeline as follows
  • e0(start of data record) -> 0
  • e1(end of data record) -> 1

Case: when 1 timestamp is received

• if timestamp is received closer to the beginning of the recording
  • e0/c0 = timestamp received
  • e1 = last timestamp in recorded file
  • c1 = c0 + (e1-e0)
• if timestamp is received closer to the end of the recording
  • e1/c1 = timestamp received
  • e0 = first timestamp in the recorded file
  • c0 = c1 - (e1-e0)

Tests

When 0 timestamps are received

• console -
• data parser -
• Timesyncs -
• timeSyncMap
  • The Map is now generated in a way that,
  • e0 = earliest emotibit timestamp in the recorded file
  • e1 = latest emotibit timestamp in the recorded file
  • c0 = 0
  • c1 = (e1-e0)/1000 (the duration of recording in S)

When 1 timestamp is received

• console -
• dataparser -
• timesyncs -
• timeSyncMap -
  • The Map generation follows the following algorithm
  • one timesync is received, e_x, c_x
    • If it closer to the start
    • e0 = e_x
    • c0 = c_x
    • e1 = latest emotibit timestamp in recoreded file
    • c1 = c_x + (e1-e0)/1000
    • It if closer to the end
    • e1 = e_x
    • c1 = c_x
    • e0 = earliest emotibit timestamp in recorded file
    • c0 = c1 - (e1 - e0)/1000
