给时光取名叫无心
[jĭ shí guāng qŭ míng jiào wú xīn]
This could imply an indifference to the passage of time—like naming time unfeeling or unintentional. The user may have a detached attitude towards the time flow. It indicates a carefree and laid-back personality, not bothered much by temporal concerns. But it also might mean that they are unwilling to linger in painful recollections of time passing by.
