Usage
timestamp = bufferVar.timestamps[N]
timestamp
The complete timestamp (including date, time, and fractional seconds) of reading
number N in the specified reading buffer when the reading was acquired
bufferVar
The reading buffer
N
The reading number (1 to bufferVar.n)
Details
The bufferVar.timestamps information from a reading buffer is only available if the
bufferVar.collecttimestamps attribute is set to 1 (default setting). If it is set to 0, you cannot
access any time information from a reading buffer.
If enabled, this buffer recall attribute is like an array (a Lua table) that contains timestamps, in
seconds, of when each reading occurred. These are relative to the bufferVar.basetimestamp for
the buffer.
Example
printbuffer(1, 6, buffer1.timestamps)
Print the timestamp of the first 6 readings
stored in buffer 1.
Example output:
07/11/2011 09:14:48.509762161,
