> Hi,

> I have discovered an inconveniance while importing intraday data into
> AmiBroker version 4.50.11. The problem occurs for the quotes with timestamp
> 00:00.

> It seems like the import code does not expect the date to roll over to a new
> day when the time rolls over from 23:00 to 00:00. An example (extract from

> "Date","Time","O","H","L","C","U","D"

> 04/21/1998,2200,1.1041,1.1057,1.1041,1.1050,16,13
