Browse source 
* guix/scripts/system.scm (profile-boot-parameters): Rename time to
  epoch to fit new procedure name.
  (epoch->date-string): Move to...
* gnu/system/boot.scm (epoch->date-string): ...here.
* gnu/machine/ssh.scm (machine-boot-parameters): Rename time to epoch.
  (machine-boot-parameters)[boot-parameters]: Use epoch->date-string.
