Converting UTC time to seconds
显示 更早的评论
I have a UTC Time stamp on my acquired data in format :
hh:mm:ss.SSSS
This data is taken at 20 ms and I need it to convert to duration in seconds and make a time series of it taking into account the start time and end time (even milli seconds taken into account)
I am currently using :
Dp = duration(hh,mm:mm,ss:ss);
tp= (minutes(D))*60;
Guidance required to make it into a time series which is generic in way that milli seconds are taken into account as well.

s = '12:34:56.789';
formatSpec = 'hh:mm:ss.SSS';
d = duration(s, 'InputFormat', formatSpec, 'Format', formatSpec)

Just call seconds.
s = '12:34:56.789';
formatSpec = 'hh:mm:ss.SSS';
d = duration(s, 'InputFormat', formatSpec, 'Format', formatSpec)
format longg
dInSeconds = seconds(d)
To check we can perform the calculations manually. To avoid the "magic numbers" 3600 and 60 I use the capability of MATLAB to convert between double and duration arrays.
secondsPerHour = seconds(hours(1)); % 3600
secondsPerMinute = seconds(minutes(1)); % 60
dInSeconds2 = secondsPerHour*12+secondsPerMinute*34+56.789
Looks pretty good to me.
