[mythtv-users] Filenames and UTC

[John Pilkington]

Since switching my main box to 0.26, and with DST now in force in the 
UK, I'm running into cases where the filename being used to access a 
recording is based on local start time, and the process fails.

One example is in my mythDVBcut script; it ought to be changed but at 
present I can correct on entry.  Another is in MythArchive:

Node = starttime, Data = 2013-04-01T20:28:00+01:00

Pre-processing recording 5: '/mnt/sam1/recb/1002_20130408202800.mpg'

Result: 34, Command was mytharchivehelper -q -q --getfileinfo --infile 
"/mnt/sam1/recb/1002_20130408202800.mpg".......

where the filename is actually 1002_20130408192800.mpg

There are clearly many ways of mending this; I looked on the wiki and 
found things like %PROGSTARTUTC%  for use in setting up a user job, but 
it isn't clear how I would use it in the cases above.

Can anyone recommend a simple general solution that already exists? 
bash and/or python wanted.

TIA
