[Feature Request]: Add ability to set a date range of displayed data

[puterboy]

Currently you can choose how many Records to load but you can't directly select the underlying timeframe displayed
As a result,

• If you load to few Records, you only see the most recent data
• If you load to many Records, it takes forever to load -- plus it still always shows the most recent data.
• Plus Records is an obscure and inconsitent proxy for time since the number of Records per time period depends strongly on whether you were printing during that time period since the polling rate changes -- so if you input a number of Records, you have no idea how much time that will cover

Solution would be that instead of selecting number of Records, you select a time window with starting/ending date and then the Records will be retrieved from that time slice.
This could either be by:

• Typing in start and end date in text boxes
• Selecting start and end dates from calendar popup
• Moving start and end of slider bar that shows the time window that will be displayed

Default could be last day or week or month (perhaps configurable)
