date mHM output

In mHM 5.10 the mHM_Fluxes_States Output starts one day later than meteo input data.

meteo input: -->starts at 1st Jan. time:units = "days since 1951-01-01-00:00:00" ; time = 0, 1, 2, 3, 4, 5, 6, 7,...

mHM-Output: -->output starts at 2nd Jan. time:units = hours since 1951-01-01 00:00:00 time = 47, 71, 95, 119, 143, 167,...

in older mHM version (5.5) from current drought monitor same meteo input generates output starting at same day as input data.

mHM-Output: -->output starts at 2nd Jan. time:units = hours since 1951-01-01 00:00:00 time = 23, 47, 71, 95, 119, 143, 167,...

warming_Days(1)    = 0
eval_Per(1)%yStart = 1951
eval_Per(1)%mStart = 01
eval_Per(1)%dStart = 01
eval_Per(1)%yEnd   = 1951
eval_Per(1)%mEnd   = 12
eval_Per(1)%dEnd   = 31

I need help to clarify this issue.
