Tvheadend doesn't follow xmltv times

Mobin

Hi. I have a xmltv EPG and I imported that to tvheadend xmltv socket but looks like tvheadend modifies xmltv times around ₃₀ minutes fast. I can't understand why tvheadend does that.

For example looks at this entry in my xmltv:

  <programme start="20240727150112 +0330" stop="20240727155357 +0330" channel="nasim">
    <title lang="fa">از سرگذشت 2</title>
    <desc lang="fa">شبکه نسیم شبکه نشاط و سرگرمی ، تارنما، www.tvnasim.ir  ،  رایانامه tvnasim@irib.ir ، تلفن 27862100  ،  صندوق پستی 1367-19395 ، پیامک 300003000</desc>
  </programme>

but in tvheadend the time for this program starts at "7/27/2024 3:30:42 PM". It's really confusing. I tested it with both EPG offset UTC and local (server) time and I'm sure the clock of my system is correct.

My timezone is "Tehran +03:30" and we recently my country doesn't use summer time-saving time anymore.
My device is Raspberry Pi 4B and I compiled tvheadend from https://aur.archlinux.org/packages/tvheadend with this config:

Configure arguments:
  --prefix=/usr --python=python3 --disable-ffmpeg_static --disable-libx264_static --disable-libx265_static --disable-libvpx_static --disable-libtheora_static --disable-libvorbis_static --disable-libfdkaac_static --disable-libav

Have you tried compiling from the original TVH source code?

tvheadend/tvheadend

I had a quick look at the XMLTV import function and it appears to support the timezone section of the date.

1) In your 'Network' configuration, have you experimented with the 'EIT time offset' value to see if that changes your result?
2) Can you configure your XMLTV data source to use UTC?

I used the current stable release v4.2.8. So there could be a fix in current master branch code?

1) I tested with both UTC and local (server) time and there was the same.
2) Yeah, I can but the problem is that looks like tvheadend doesn't have "UTC+0330" which is my timezone (There is UTC+3 but not +3:30) for EIT time offset.

Mobin So there could be a fix in current master branch code?

I'm not sure, but v4.2 is very old. I looked at the latest code and it appeared to process the TZ.

Mobin 2) Yeah, I can but the problem is that looks like tvheadend doesn't have "UTC+0330" which is my timezone (There is UTC+3 but not +3:30) for EIT time offset.

I meant get your XMLTV provider to supply UTC instead of your local time. I am at UTC+10, but my XMLTV provider always supplies times in UTC, not local time.

I will try to supply with UTC time

Looks like it's fixed 🙂 but it's still a bug that tvheadend does mess-up times for no reasons. Maybe I will open a bug in bug tracker for this.

Thanks mate 🙂 Have a great time.

Mobin but it's still a bug

The bug was fixed in January 2018. I checked the source that you stated in your original post and it pre-dates the bug fix. You are running an old version of TVH.
