I've got a script running from startup on my raspberry pi using
and
but when I grab a video and timestamps the filename it uses the same timestamp over and over. If I run it manually it puts the correct timestamp, so I think it grabs it once when the script is started but not each time it needs to timestamp, if you get what I mean??
so basically, how can I have it grab the correct timestamp instead of just once when the script is run at startup?
this is my full code:
1 |
import time |
1 |
timestamp = time.strftime( "%Y-%m-%d_%H:%M:%S" ) |
