write header of sac for b and e

[yjgao-gfz]

Hello, dear experts.
Here I am trying to write the b and o to sac files through obspy, but when I read the saved sac after writing, it didn't change, is it a bug?
Best regards,
yjgao

• Please check whether the bug was already reported or fixed.
• Please provide the following information:
  • ObsPy version, Python version and Platform (Windows, OSX, Linux ...)
  • How did you install ObsPy and Python (pip, anaconda, from source ...)
  • If possible please supply a short, self contained, correct example that
    demonstrates the issue.
  • If this is a regression (used to work in an earlier version of ObsPy),
    please note when it used to work.
• Please take the time to format your ticket appropriately
  (e.g. put error tracebacks into code blocks)

Hi,

Could you paste a minimum working example illustrating the problem you're having? I'm happy to look into this if I can see what you're doing.

Thanks!
