How to parse them into se

Answer 1

A version for Python:

ex=[
    '21-18:26:30',
    '06-00:15:30',
    '15:28:37',
    '48:14',
    '00:01'
    ]

def etime_to_secs(e):
    t=e.replace('-',':').split(':')
    t=[0]*(4-len(t))+[int(i) for i in t]
    return t[0]*86400+t[1]*3600+t[2]*60+t[3]

for e in ex:
    print('{:11s}: {:d}'.format(e, etime_to_secs(e)))
