* This is DataComponent specifically for converting |

* time since epoc dates into a nice format. |
| 13 |

| 14 |
* As this is essentially just string data we just |
| 15 |
* extend StringDataComponent, intercepting the value |
| 16 |
* to convert it. |
| 17 |
* |
| 18 |
* It uses the JProgressBar to display the value. |
