问题 I have a database where I save time as time() from php, which is seconds since 1 jan 1970 . Is there any way I can convert, for example 2012-12-12 to seconds since 1 jan 1970 ?

I am trying to find the maximum number of concurrent transmissions based on these two timestamps . I have a working query but it is both slow and extremely cumbersome.

I've just tried several hundreds (if not thousands...) of RegEx's available to get what I want... But none of them worked. I'm simply looking for a Regular expression, that represents a TimeSpan days.hours:minutes:seconds : 7.00:00:00 would represent "7 Days" This one sadly doesn't work: (\d\d).(\d\d):(([0-6][0])|([0-5][0-9])):(([0-6][0])|([0-5][1-9])) That's because your Regex pattern is expecting 2 digits for days and you only have 1 digit. Just make the first digit optional with ? (\d?\d)\.(\d\d):(60|([0-5][0-9])):(60|([0-5][0-9])) or better yet just use + to match one or more because that

For example one TimeShift where: Start: 07:00 End: 23:30 then that means 16.5 hours. For the examples above: Range 1: 11 hours Range 2: 5 hours Range 3: 0.5 hours 回答1: Here
