Help Decode Photo filename timestamp etc?

[ekorpinen]

Im trying to decode the filename to find when i took a picture. The EXIF data is blank but thats a differenct problem. The pictures are taken on a droid RAZR

example: 2012-07-279519-51-5295191

ok I get the first part 2012-07-27 was the data taken leaving

9519-51-5295191

what do these translate into?

Any help is greatly appreciated.
