+Subject: [PATCH hurd 2/4] libshouldbeinlibc/maptime: provide a mapped time
+ source
+
+Automatically map an appropriate time device.  I don't see any need to
+customize this process, so we might as well just use the default one
+everywhere.
+
+* libshouldbeinlibc/maptime.c (maptime_default_mtime): New variable.
+(maptime_init): New function that initializes `maptime_default_mtime'
+at load time.
+* libshouldbeinlibc/maptime.h (maptime_default_mtime): New declaration.
