Got a script which i need to subtract 25 minutes from, essentially at the moment data is being gathered from a SQL database when being input/plotted into an Excel spreadsheet. The time on the spreadsheet needs to be 25 minutes sooner than what the SQL Database outputs - What i've got at the moment is below.

PHP Code


<?php 
plotsheet.write(ssrow,1,sector['std'].strftime("%H:%M"), boldformat) 


Can't seem to find any documentation on strftime which explains what i want, i assume it needs to look something like the below, although its not working:

PHP Code


<?php 
plotsheet.write(ssrow,1,sector['std'].strftime("%H:%M - 15M"), boldformat) 


Any suggestions?


TIA  🤝

You can find info on strftime here:
https://docs.python.org/2/library/datetime.html#strftime-strptime-behavior
http://strftime.org/

But I'm not entirely sure what you're trying to do. Do you want to take the current time (the time the script is being executed) and subtract 25 minutes from it, then write
it into a spreadsheet? Or get a time from a SQL DB then sub 25 mins from that and write it into a spreadsheet?

Either way strftime() won't really help you there, it only gives you a string representation of a date object in a specified format. And "-15M" isn't a format specifier.
I think what you need is the timedelta() function (also documented in the link above).

Code

from datetime import datetime
from datetime import timedelta

now = datetime.today() #gives you current time
earlier = now - timedelta(minutes=25) # subtract 25 mins from now
strtime = earlier.strftime("%H:%M") #format the datetime object into a string
