-- Get parsed timer data

-- Returns the parsed timer data (i.e. all variables are replaced with their
-- respective values) for the given player referenced by the name.
--
-- The returned table holds the formatted version as well as the individual
-- times (session start, current date, etc.) as configured via the respective
-- dialogs. This will be used for the Timer itself as well as in the
-- configuration formspec.

-- @param player_name The name of the player to get the timer data for
-- @return table The timer data of the player
