The issue timetracking "Logged" field does not always match the sum of all time entries to an issue.
There is a field that shows how much time is logged to an issue under "Time Tracking" on the issue screen. I believe this is mapped to the DB field jiraissue.TIMESPENT, and must be calculated internally as it can't be changed. In some strange cases (around .2% of issues on our server), this value doesn't always match the sum of all time entries (worklog.timeworked in the DB) for the issue. The issue screen also shows collaborators and their total time, and when their totals are added together, they don't match the total "Logged" (They do match the total of worklog.timeworked). Notice collaborators add up to 437.25, not 434.25:
Of the .2% of issues like this, most of them have a "Logged" value that is too big, but some of them have one that is too small. The values are also usually not too far off, but the fact that they aren't the same at all confuses me. What is causing this discrepancy? and what is the true value of the time logged to an issue?
