Type TSP-Link accessible
Attribute (R) Yes
Usage
basetime = bufferVar.basetimestamp

Details
This read-only attribute contains the timestamp (in seconds) of the first reading stored in a buffer
(rb[1] stored in reading buffer rb). The timestamp is the number of seconds since 12:00 am
January 1, 1970 (UTC) that the measurement was performed and stored.
For dedicated reading buffers, all buffer attributes are saved to nonvolatile memory only when the
reading buffer is saved to nonvolatile memory.
See the smua.nvbufferY attribute for details on accessing dedicated reading buffers.
Example
basetime = smua.nvbuffer1.basetimestamp
print(basetime)
Read the timestamp for the first reading stored in dedicated reading buffer 1.
Output:
1.57020e+09
This output indicates that the timestamp is 1,570,200,000 seconds (which is Friday, October 4, 2019 at
14:40:00 pm).
