read_excel can't read datetime values

read_excel from SWAT works different that read_excel from Pandas, wich makes me unable to read Date column as a Datetime value.

SWAT: storm_damage = conn.read_excel("D:\Workshop\VIYAPY\storm.xlsx", sheet_name="Storm_Damage", casout=dict(name="STORM_DAMAGE", replace=True, caslib="Public"))
It reads Date column as Varchar

Pandas: sd = pd.read_excel("D:\Workshop\VIYAPY\storm.xlsx", sheet_name="Storm_Damage")
It reads Date column as datetime64

I've tried explicity use converters and it is not helping:

SWAT: storm_damage = conn.read_excel("D:\Workshop\VIYAPY\storm.xlsx", sheet_name="Storm_Damage",
casout=dict(name="STORM_DAMAGE", replace=True, caslib="Public"),
converters={'Date': pd.to_datetime})

Pandas: sd = pd.read_excel("D:\Workshop\VIYAPY\storm.xlsx", sheet_name="Storm_Damage", converters={'Date': pd.to_datetime})

Anything I do I see the action run is:
NOTE: 20: action table.loadTable / path='_f_c15dc565_7ff582b29b88.csv', readAhead=true, importOptions={fileType='csv', vars={Cost={type='double'}, Date={type='varchar'}, Event={type='varchar'}, Summary={type='varchar'}}, locale='EN-us'}, resident=true, promote=false, caslib='_LIB_C15DC565_7FF582B29B88', casOut={name='STORM_DAMAGE', caslib='Public', replace=true}, singlePass=false, noSource=true;

Inizia dal punto di ingresso conn.read_excel ed esamina l'azione table.loadTable registrata, in particolare il tipo varchar della variabile Date e le opzioni di importazione CSV. Riproduci la cartella di lavoro segnalata e verifica che la colonna Date venga caricata come valore datetime, preservando il comportamento esistente di read_excel per le altre colonne.
