Neel Natu commented on MYNEWT-4:
--------------------------------

Pull request: https://github.com/apache/incubator-mynewt-larva/pull/8

Here's the test plan that I executed (it should eventually make it into the test package):

year:
common case, 9999, 1970, less than 1970, greater than 9999,
non-numeric chars in string, number of digits != 4

invalid delimiter (not '-') between year and month

month:
all legal months (01-12), illegal months (00, 13, 43 etc),
non-numeric characters in the month, number of characters not equal to 2.

invalid delimiter (not '-') between month and day

day:
all days legal for the month/leapyear
non-numeric characters in the 'day' field
0, 1 or more than 2 characters in the 'day' field

invalid delimiter (not 'T') between date and time

hour:
all legal values (00-23)
non-numeric characters in the 'hour' field
0, 1 or more than 2 characters in the 'hour' field
invalid delimiter (not ':') between the hour and min fields.

min:
all legal values (00-59)
non-numeric characters in the 'min' field
0, 1 or more than 2 characters in the 'min' field
invalid delimiter (not ':') between the min and sec fields.

sec:
all legal values (00-59)
non-numeric characters in the 'sec' field
0, 1 or more than 2 characters in the 'sec' field
invalid delimiter (not '.') between the 'sec' and 'usecs' fields

fracsec:
test with 0 digits (error)
test with 7 or more digits (error)
test between 1 and 6 digits (success)

timezone:
Legal values 'z' or 'Z' after sec or fracsec
Legal values +HH:MM or -HH:MM after sec or fracsec
Additional characters after 'z' or 'Z'
Additional characters after +HH:MM or -HH:MM

> Right now all time is relative, either using OS time (which is a 1ms tick), or cputime, which allows for high resolution timers.
> There needs to be a concept of "real" / "wallclock" time.  Time should be kept in a 64-bit value, and both 64-bit and 32-bit APIs should be created to allow access to time.
