Combine the brandy, sugar and water in a small saucepan. Place over medium-high heat and bring to a simmer, whisking constantly until the sugar dissolves, about 5 minutes. Remove from heat and add the rose water and thyme. Combine the brandy mixture and the apricots in a sterilized 1-liter container and seal. Allow the contents to cool to room temperature before transferring to the refrigerator. Chill for at least 3 days before using. The apricots will keep for up to 1 month.
