User wants to know why a consultant's hours entered for a specific date are different from the Client Hours for the same date.
This most likely happens because of the 'Apply to Client Hours only' option found in Global Settings > Time & Expenses. This option applies the smallest time increment in Core to Client Hours only and not the actual hours recorded. For example, if the smallest time increment is set to 0:15 (15 mins = .25 hours) and you enter 7.21 in Hours, Core copies 7.25 Hours to Client Hours, changing to the nearest value allowed by the time increment. To keep the hours the same, uncheck the option that applies the time increment to Client Hours only.
