Ariadne - Technical description
In case when no automated time registration system is available, or when this system is out of order, manual input of start and finish times is required.
Manually entering start and finish times is a job which takes concentration . You get the start and finish times most often via telephone or portophone. Sometimes you get the times via paper notes. When you get the time values via phone, the speech quality is in many cases poor. You have to concentrate on the time values you receive, and to enter them instantaneous. This process is error prone.
The requirements for back time entry are 1) enter start number and time instantaneous when you hear it over the phone, and 2) being able to check and correct what you entered. 3) Manual time measurement measures in hours-minutes-seconds-milliseconds (c.f. stopwatch).
For the backup time entry, the T510-Run table is extended with start and finistimes, hh-mm-ss-ms:
These requirements are met in F550-Rundata-entry.
