The fix is different depending on the OS and offset needed. I'll give you the fix for EST. For Kodi 16.x go into pvr settings and under EPG settings, change EPG Time Shift (hours) to -4.00 and tic the box below to Apply Time Shift To All Channels.
For Kodi 17.3, make the EPG Time Shift to +1.00.
Hope that helps.
