Maybe it's a bug in the ISDB parser (you use that in South America, right)?

It needs more accurate description. Which time is used by stream providers? Local time? What about DST ? Actually, tvh expects that the broadcasted times are in GMT+0 as specified in ETSI EN 300 468 V1.4.1 .

yes, we use it in most south america countries

how can i check the time used by stream providers ? is there a way to get a dump of the grabbing ? the only grabber enabled is the EIT: dvb grabber

i have been doing some fiddling and if i set ubuntu timezone to gmt+0 and manually set the time then EPG works properly, not sure if it means anything..

I just captured this with dvbsnoop, the program "desde la tierra" shown in this event, has a reported "Start_time: 0xdecf060000 [= 2015-01-17 06:00:00 (UTC)]" and it is shown in the epg listing as starting sat 17 january at 3 am.. the program actually starts at 6 am gmt-3 according to the channel's website.. so if Im not mistaken, they are providing EPG info with wrong times...

It appears like a local time instead UTC. Could you try v3.9-2372-geb5cfaa ? Set "EIT Local Time" in the network settings (it's advanced so it's only in Edit dialog).

thanks a lot!, it works like a charm...
