No "specific" time frame

"if the throttles are moved to the reverse range with a movement which is too rapid, it is possible to lose control of the aircraft before a propeller malfunction can be detected."

"The movement from the flight range to the reverse range should be made at a reasonable rate which will permit detection of a malfunction, such as failure of the low pitch stop to retract."

Also it should be noted that a “Slower†movement can cause the LPS to retract at various times causing uneven aerodynamic loads on the aircraft as each propeller enters the ground range.

Remember reversing propellers at speeds of 115 KIAS or above could result in engine flame out.

Quoting:

“NOTEâ€

Retarding the throttles below FLIGHT IDLE at air speed above approximately 115 KIAS could result in power-loss/bog-down on one or more engines, particularly when operating in high ambient temperature condition. … (Ref. TO 1C-130H-1) sec2 page79

Quoting:

(HOT WEATHER PROCEDURES) (LANDING)

“CAUATIONâ€

Rapid movement of throttles in the reverse range can cause unscheduled engine rundown/RPM decay. (Ref. FM 382C-14E) sec2 page 92

Long time, during simulator training (hot weather) if reverse above 90 KIAS the four engine will bog-down. I do not know if the 90 comes through reference or it is just the setting of the simulator.
