The clock on Cmdr. Riker's wall gives the stardate as 46154.4 and the time as 10:37:41. The ".4" at the end of the stardate, is a decimal (base 10) reflection of how far through the current day it is, with each 0.1 representing one tenth of the day (2 hours and 24 minutes). Without the actual time given, the stardate alone narrows the time to between 09:36 to 11:59.
Ensign Rager gets a first name in this, Sariel.
