Candidate passages:
In the Army Reserve and National Guard, a service member qualifies for the medal after completing a total of ten years service in the active reserve.
This service may be cumulative, provided that the combined ten years of service was performed over a period of twelve consecutive years.
Voluntary recalls to active duty are not counted within the ten years of service.
In addition, unlike the Reserve Good Conduct Medal, a service member’s disciplinary history is not a factor when awarding the Armed Forces Reserve Medal.
In the Naval Reserve, members of the Individual Ready Reserve are eligible for the medal after 10 years of service.
Periods of service for the Armed Forces Reserve Medal are denoted through the use of the hourglass device.
The length of the period for which the Armed Forces Reserve Medal is awarded is indicated using a bronze hourglass, silver hourglass, gold hourglass, or bronze and gold hourglasses together.
The initial presentation of the Armed Forces Reserve Medal is authorized with the bronze hourglass device denoting ten years of reserve service.
At twenty years of service, the hourglass is upgraded to silver and at thirty years the hourglass becomes gold.
For those who complete forty years of reserve service, a gold and bronze hourglass device are worn simultaneously.
This is the only case where hourglasses are worn together; in all other cases the hourglass device is upgraded to the next higher award degree and is worn as a single device.
Prior to Executive Order 13013 issued on August 6, 1996, a bronze hourglass device was presented only upon the second and subsequent awards of the Armed Forces Reserve Medal, as in a bronze hourglass for twenty years of service, two bronze hourglasses for thirty, and three bronze hourglasses for forty.
Executive Order 13013 provided awarding a bronze hour glass after 10 years service, a silver hourglass after 20 years of service and a gold hourglass after 30 years of service.
Personnel discharged or retired, prior to the change of the Hourglass Device award criteria, are not eligible for a correction of records or an upgrade of the Hourglass Device, as the Hourglass Device would have originally been presented under the original award specifications. 
Victorian wasp waist hourglass corset was very unhealthy, as opposed to the modern wasp waist hourglass corset.
With a modern hourglass corset, the stomach is "over" the waistline, whereas with a Victorian hourglass corset, the stomach is "in" the waistline.
The flat front panels of the "health corset" or S-shaped corset in the later Victorian/Early Edwardian period did, in fact, not force the stomach in, but did alter posture.  
Sterling Fry took up the Time Commander name after his mentor, John Starr, was killed.
He kidnapped Liberty Belle in an attempt to steal Hourman's hourglass.
Time Commander beat Hourman and took the hourglass from him.
After releasing the tachyon particles from the hourglass, Fry disappeared.
Whether his exposure to the particles killed him or not is not known at this time.
Time Commander appears in "Justice League of America 80-Page Giant" #1 (Nov 2009), in which he rescues the League, who have been scattered through time by Epoch.
Although he appears to be acting as a hero, it transpires that in addition to acquiring Epoch's time displacement gauntlet, he also recovered the original Time Commander's hourglass from the JLA trophy room.
Due to the nature of time travel, it is not clear if this Time Commander is Starr, Fry or a new character. 
The origin of the hourglass is unclear, although it may have been introduced to Europe by an 8th-century monk named Luitprand, who served at the cathedral in Chartres, France.
It was not until the 14th century that the hourglass was seen commonly, the earliest firm evidence being a depiction in the 1338 fresco "Allegory of Good Government" by Ambrogio Lorenzetti.
Unlike its predecessor the clepsydra, or water clock, which may have been invented in ancient Egypt, the hourglass is believed to have originated in medieval Europe.
This theory is based on the fact that the first written records of it were mostly from logbooks of European ships.
Written records from the same period mention the hourglass, and it appears in lists of ships stores.
An early record is a sales receipt of Thomas de Stetesham, clerk of the English ship "La George", in 1345:"The same Thomas accounts to have paid at Lescluse, in Flanders, for twelve glass horologes (" pro xii.
orlogiis vitreis "), price of each 4½ gross', in sterling 9"s." Item, For four horologes of the same sort (" de eadem secta "), bought there, price of each five gross', making in sterling 3"s." 4"d."" Hourglasses were very popular on board ships, as they were the most dependable measurement of time while at sea.
Unlike the clepsydra, the motion of the ship while sailing did not affect the hourglass.
The fact that the hourglass also used granular materials instead of liquids gave it more accurate measurements, as the clepsydra was prone to get condensation inside it during temperature changes.
Seamen found that the hourglass was able to help them determine longitude, distance east or west from a certain point, with reasonable accuracy.
The hourglass also found popularity on land as well.
As the use of mechanical clocks to indicate the times of events like church services became more common, creating a 'need to keep track of time', the demand for time-measuring devices increased.
Hourglasses were essentially inexpensive, as they required no rare technology to make and their contents were not hard to come by, and as the manufacturing of these instruments became more common, their uses became more practical.
Hourglasses were commonly seen in use in churches, homes, and work places to measure sermons, cooking time, and time spent on breaks from labor.
Because they were being used for more everyday tasks, the model of the hourglass began to shrink.
The smaller models were more practical and very popular as they made timing more discreet.
After 1500 A.D., the hourglass was not as widespread as it had been.
This was due to the development of the mechanical clock, which became more accurate, smaller and cheaper, and made keeping time easier.
The hourglass, however, did not disappear entirely.
Although they became relatively less useful as clock technology advanced, hourglasses remained desirable in their design.
Some of the most famous hourglasses are the twelve-hour hourglass of Charlemagne of France and the hourglasses of Henry the VIII of England, made by the artist Holbein in the 16th century.
The oldest known surviving hourglass resides in the British Museum in London.
Not until the 18th century did the Harrison brothers, John and James, come up with a marine chronometer that significantly improved on the stability of the hourglass at sea.
Taking elements from the design logic behind the hourglass, they were able to invent a marine chronometer that was able to accurately measure the journey from England to Jamaica, with only a miscalculation of five seconds, in 1761. 
The Calendar Man freed Starr from prison to join with the Clock King and Chronos as the Time Foes.
The villains aimed to recover the Hourglass, but were prevented by the Team Titans.
In truth, the entire scheme had been secretly masterminded by a future-time villain, Lazarium.
The Time Foes are featured in "Team Titans" #14 (Nov 1993), heading into the Hudson River Mall.
Their goal is to retrieve Starr's valued hourglass.
They go relatively unnoticed, as Halloween costumes are prevalent that day.
Attention is only brought to them when Starr smacks a woman who was confronting him over purchasing the hourglass.
The heroes swiftly confront the villains.
Calendar Man asks Starr to use his hourglass in battle.
He claims he cannot do it, as it is an instrument for good (despite him having used it to smack around the heroine Redwing moments earlier).
Also, the hourglass is broken.
Starr is not seen actually fighting in the resulting battle, he is admonished later by his captured allies for just having surrendered.
Starr explains he is misunderstood, at heart he is a peaceful man.
As a result of the "Zero Hour" crisis in time, the Time Foes became stuck in a temporal loop.
Unable to free himself or his teammates, John Starr seemed doomed to perish there.
