How do I reformat this date variable?

[Mastiff]

I have a bunch of temp sensors tied into the webserver, and there's only one annoyance. My dates comes out like this:

Code: Select all

2013-12-07 11:30:48

I would very much like to unclutter it and reformat it to this:

Code: Select all

11:30, 07.12.

Can somebody please tell me how? Thanks in advance!

If it is certain, that timestring is always the same length (for example as 2013-12-07 00:00:01), then you can do it like this ("t" is old timestring):

Code: Select all

newT = "%s:%s, %s.%s." % (t[11:13], t[14:16], t[8:10], t[5:7])

Thank you very much for the answer! Unfortunately my thick skull is messing it up, it seems... I get these errors:

Code: Select all

13:42:49            Traceback (most recent call last):
13:42:49              Python script "44", line 15, in <module>
13:42:49                Ute_time_formatert = "%s:%s, %s.%s." % (Ute_time[11:13], Ute_time[14:16], Ute_time[8:10], Ute_time[5:7])
13:42:49            NameError: name 'Ute_time' is not defined

I thought I had definded the Ute_time in line 11 of the the script, here in bold. This is the little script that's run:

Code: Select all

import time
eg.event.payload_copy = eg.event.payload
my_data = eg.event.payload_copy.split(' ')

td = my_data[2] #temperature
tf = my_data[6] #humidity

timeStamp = str(
time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
)
[b]eg.globals.Ute_time = timeStamp[/b]
eg.globals.Ute_temp = td
eg.globals.Stua_fukt = tf

Ute_time_formated = "%s:%s, %s.%s." % (Ute_time[11:13], Ute_time[14:16], Ute_time[8:10], Ute_time[5:7])

I'm guessing that I've misunderstood something about how the variables are logged. I tried to look for a place in EG that shows all variables, but I couldn't find it.

You need to use the full name of the variable "eg.globals.Ute_time" or it won't work.

Thank you! Got it working.

Would this not be a bit simpler?

Code: Select all

import time
eg.event.payload_copy = eg.event.payload
my_data = eg.event.payload_copy.split(' ')

td = my_data[2] #temperature
tf = my_data[6] #humidity

timeStamp = str(
time.strftime("%H:%M, %d.%m.", time.localtime())
)
eg.globals.Ute_temp = td
eg.globals.Stua_fukt = tf
