I also suggest splitting convertValue into two functions, one that takes
strings and one that takes numbers. A lot easier to read and maintain.

FWIW you could dispense with reverse in convertValue by testing the type of
value for int or str.
    

Thanks for feedback and suggestions. Below is the function split in 2.

def convertToString(value, dateformat):
    print value
    if type(value) == int:
        return str(value)
    else:
        try:
            return strftime(dateformat, value)
        except TypeError:
            return value

def convertFromString(value, dateformat):
    try:
        return int(float(value))
    except ValueError:
        try:
            return strptime(value, dateformat)
        except:
            return value

Yes - that is what we had in mind. FWIW you can simplify slightly:
def convertToString(value, dateformat):
    print value
    if type(value) == int:
        return str(value)
    try:
        return strftime(dateformat, value)
    except TypeError:
        return value
