Covert Time to UNIX Time

Here is a Expression rule that you may use to convert time to a UNIX timestamp. It makes use of the fact that the difference between two datetimes is an interval. I have used it to convert the current datetime (now()) to UNIX timestamp
with(

local!unixEpoch : fn!datetime(1970, 1, 1, 0,0,0,0),

local!intervalDiff: fn!now() - local!unixEpoch,

local!stringintervalDiff: fn!tostring(local!intervalDiff),

local!days: fn!tointeger(local!intervalDiff),

local!stringPartExcludingDays: fn!split(local!stringintervalDiff, "::")[2],

local!splitPartExcludingDays: fn!split(local!stringPartExcludingDays, ":"),


local!hours: fn!tointeger(local!splitPartExcludingDays[1]),

local!minutes: fn!tointeger(local!splitPartExcludingDays[2]),

local!seconds: fn!tointeger(local!splitPartExcludingDays[3]),

local!days*24*3600 + local!hours*3600 + local!minutes*60 + local!seconds

)
