Confusion Over True Love Transmission

There is now some confusion over the date and time that David Tennant's new BBC One drama, True Love, will air.
Last week both the BBC Media Centre and Working Title Films stated that David's episode of True Love would air on Monday 18th June at 10.35pm, but now the Radio Times is listing the episode, which is entitled 'Nick' after the charater that David portrays, as being shown at 10.25pm on Sunday 17th June.
Incidently the trailer for the series just states that it is coming soon...
