The Start Time panel indicates when you want the reservation to begin. There are three choices.
Current Time: If you select Current Time, the reservation, if accepted, begins immediately. To select the present as a start time click the radio button on the left.
Future time: If you want the reservation to start in the future, enter the Year, Month, Day, Hour, and Minute at which you want the reservation to start. You must make sure that the date is valid (not February 30th, for example). Should you inadvertently enter an invalid date, Merkato attempts to determine your intent and present an equivalent valid date. If this is not what you intended to specify, refuse the reservation and return to the date selection window. To select a future start time, enter the time and click the radio button on the left.
End time of a reservation: If you have already created one or more reservations, they appear in this pull-down list. You can select the end of one of these existing reservations as the start time of the new reservation you are making. Select it from the list and click the radio button on the left.
