FreeOTP: TOTP - enhancement proposal

Hi, for TOTP tokens, would it be possible to add a timeoffset in seconds? If you have a hardware token and know the seed of it, you could then use FreeOTP and the hardware token in parallel. Hardware token clocks tend to be faster or slower than the current time, and servers checking the values usually keep track of the offset a token has (usually the offset slowly increases or decreases), and they accept a value only in a small time window (i.e. 2 minutes plus or minus). If the hardware token in that situation has accumulated an offset of 4 minutes, FreeOTP values are these 4 minutes off from the value which the server checking the value expects - in one direction, you'd have to wait for 4 minutes until you could use the FreeOTP value -- in the other direction you are out of luck (the value checked for is 4 minutes "in the future"). A configurable offset would be the easiest way to help there. Adjusting the time of the device FreeOTP runs on to the time the hardware token internally uses is no real alternative ;-). Best regards, Juergen.
